It sounds fancy, but it's really quite simple and it is a computational stepping stone to many other interesting concepts like correlation. This video describes covariance, what it does and doesn't do, how it's computed, and why it is more useful as a computational stepping stone rather than an end in itself.

null | null | null | null | null | Expected Values for Continuous Variables!!! | 2021-06-22 | If you ever muck around in statistics, it's not long before you see E(x) = something. These are expected values. Expected Values for Continuous Variables are a little trickier than their discrete counterparts because we have to do some calculus. However, I'll walk you through it, one step at a time, so don't sweat it! BAM!
NOTE: This one is, believe it or not, pretty near to my heart. When I was taking Statistical Theory in graduate school (from Rodger Berger of Casella and Berger, who wrote the standard textbook on statistical theory, "Statistical Inference") I remember having a lot of trouble with expected values. They intimidated me for two reasons 1) deriving them seemed like total luck and 2) I never understood, exactly, what the formula for continuous variables meant in a deep way. I could look at the equation and name the parts, but that was all I could do. Anyway, fast forward a few years and here I am, going back to these basics, this time determined to get that "deep understanding" I missed before, and, at least for myself, I succeeded. And I hope that means other people will also be able to get a deep understanding of expected values as well.
NOTE: This StatQuest assumes that you are already familiar with the concept of an Expected Value. If not, check out the 'Quest: https://youtu.be/KLs_7b7SKi4

null | null | null | null | null | Bootstrapping Main Ideas!!! | 2021-07-06 | Bootstrapping is one of the simplest, yet most powerful methods in all of statistics. It provides us an easy way to get a sense of what might happen if we could repeat an experiment a bunch of times. It turns point estimates into distributions that can be used to calculate all kinds of stuff, including standard errors, confidence intervals and even p-values. In this video, we show how it can be used to calculate standard errors and confidence intervals. In Part 2, we'll see how to calculate p-values.

null | null | null | null | null | Quantile-Quantile Plots (QQ plots), Clearly Explained!!! | 2017-11-13 | Quantile-Quantile (QQ) plots are used to determine if data can be approximated by a statistical distribution. For example, you might collect some data and wonder if it is normally distributed. A QQ plot will help you answer that question. You can also use QQ plots to compare to different datasets that you collected to determine if their distributions are comparable. This video shows you how to do both things.
NOTE: The data in this video are measures of gene expression. If "gene expression" doesn't mean anything to you, just imagine that the data represents how tall a bunch of people are, or how much they weigh. Then consider the y-axis to be the height or weight of the people, and the x-axis just represents all of the data you collected on a single day. In this case, all of the data were collected on the same day, so they form a single column.

It sounds fancy but is really super simple. Essentially you just sort each sample data from high to low. If your samples are rows, you then replace the values with the average of each row. BAM!

null | null | null | null | null | Probability is not Likelihood. Find out why!!! | 2018-03-09 | NOTE: This video was originally made as a follow up to an overview of Maximum Likelihood https://youtu.be/XepXtl9YKwc . That video provides context that gives this video more meaning.
Here's one of those tricky little things, Probability vs. Likelihood. In common conversation we use these words interchangeably. However, statisticians make a clear distinction that is important to understand if you want to follow their logic. The good news is that they are both super simple. The bad news is that they are easy to get mixed up. The StatQuest gives you visual images that make them both easy to remember so you'll always keep them straight.

8:53 I meant to say "the remaining 198.7 people without the mutated gene".
14:27 I correctly wrote "If the tests worked as expected, 5% should have p-values less than 0.05". That is correct. However, when recording the voiceover, I said "5% should have p-values less than 0.5", which is not correct.

Statistics Fundamentals: The Mean, Variance and Standard Deviation
https://youtu.be/SzZ6GpcfoQY
In it, we show exactly why, when we estimate the variance, dividing by 'n' underestimates the value we are interested in. It also describes why we square each term instead of taking the absolute value. The visuals used in this StatQuest make it easy to remember why we should divide by n-1, and this will save us from falling into a very common pitfall.

null | null | null | null | null | Machine Learning Fundamentals: Bias and Variance | 2018-09-17 | Bias and Variance are two fundamental concepts for Machine Learning, and their intuition is just a little different from what you might have learned in your statistics class. Here I go through two examples that make these concepts super easy to understand.

4:06 Definition of Variance
5:10 Definition of Overfit
Correction:
4:06 I say that the difference in fits between the training dataset and the testing dataset is called Variance. However, I should have said that the difference is a _consequence_ of variance. Technically, variance refers to the amount by which the predictions would change if we fit the model to a different training data set.

null | null | null | null | null | ROC and AUC, Clearly Explained! | 2019-07-11 | ROC (Receiver Operator Characteristic) graphs and AUC (the area under the curve), are useful for consolidating the information from a ton of confusion matrices into a single, easy to interpret graph. This video walks you through how to create and interpret ROC graphs step-by-step. We then show how the AUC can be used to compare classification methods and, lastly, we talk about what to do when your data isn't as warm and fuzzy as it should be.
NOTE: This is the 2019.07.11 revision of a video published earlier.

Confusion Matrices...

null | null | null | null | null | Entropy (for data science) Clearly Explained!!! | 2021-08-25 | Entropy is a fundamental concept in Data Science because it shows up all over the place - from Decision Trees, to similarity metrics, to state of the art dimension reduction algorithms. It's also surprisingly simple, but often poorly explained. Traditionally the equation is presented with the expectation that you memorize it without thoroughly understanding what it means and where it came from. This video takes a very different approach by showing you, step-by-step, where this simple equation comes from, making it easy to remember (and derive), understand and explain to your friends at parties.

Last time we saw how to fit a squiggly line to the data. This time we'll learn how to evaluate if that squiggly line is worth anything. In short, we'll calculate the R-squared value and it's associated p-value.

null | null | null | null | null | Regularization Part 1: Ridge (L2) Regression | 2018-09-24 | Ridge Regression is a neat little way to ensure you don't overfit your training data - essentially, you are desensitizing your model to the training data. It can also help you solve unsolvable equations, and if that isn't bad to the bone, I don't know what is.

null | null | null | null | null | Regularization Part 3: Elastic Net Regression | 2018-10-08 | Elastic-Net Regression is combines Lasso Regression with Ridge Regression to give you the best of both worlds.

null | null | null | null | null | StatQuest: Principal Component Analysis (PCA), Step-by-Step | 2018-04-02 | Principal Component Analysis, is one of the most useful data analysis and machine learning methods out there. It can be used to identify patterns in highly complex datasets and it can tell you what variables in your data are the most important. Lastly, it can tell you how accurate your new understanding of the data actually is.
In this video, I go one step at a time through PCA, and the method used to solve it, Singular Value Decomposition. I take it nice and slowly so that the simplicity of the method is revealed and clearly explained.
If you are interested in doing PCA in R see: https://youtu.be/0Jp4gsfOLMs

null | null | null | null | null | StatQuest: MDS and PCoA | 2017-12-11 | MDS (multi-dimensional scaling) and PCoA (principal coordinate analysis) are very, very similar to PCA (principal component analysis). There really only one small difference, but that difference means you need to know what you're doing if you're going to use MDS effectively. This video make sure you learn what you need to know to use MDS and PCoA.
There is a minor error at 4:14: The difference for gene 3 should be (2.2 - 1)². Instead the distance for gene 2 was repeated.

null | null | null | null | null | StatQuest: t-SNE, Clearly Explained | 2017-09-18 | t-SNE is a popular method for making an easy to read graph from a complex dataset, but not many people know how it works. Here's the inside scoop.
Here’s how to create a t-SNE graph in R (this is copied from the help file for Rtsne)…
library("Rtsne")
iris_unique <- unique(iris) # Remove duplicates
iris_matrix <- as.matrix(iris_unique[,1:4])
set.seed(42) # Set a seed if you want reproducible results
tsne_out <- Rtsne(iris_matrix) # Run TSNE
# Show the objects in the 2D tsne representation
plot(tsne_out$Y,col=iris_unique$Species)
This StatQuest is based on the original t-SNE manuscript, and it's not super hard to read (especially if you understand the general idea of how it works): https://lvdmaaten.github.io/publications/papers/JMLR_2008.pdf

Corrections:
6:17 I should have said that the blue points have twice the density of the purple points.
7:08 There should be a 0.05 in the denominator, not a 0.5.
