# Bayes Linear Regression - understanding the posterior formula?
In the linked resource, the author defines the posterior probability of Bayesian linear regression as:
P(B|y,X) = P(y|B,X)*P(B|X)/P(y|X)
I have a couple questions/issues with this.
First, B represents the weight(s) vector, but it shouldn't include th... | {} |

How do you solve -9(-a – 1) = 8a + 14?
$a = 5$
Explanation:
From the given
$- 9 \left(- a - 1\right) = 8 a + 14$
$9 a + 9 = 8 a + 14$ by distributive property
$9 a + 9 - 8 a = 8 a + 14 - 8 a$ subtraction property
$a + 9 = 14$
$a + 9 - 9 = 14 - 9$ subtraction property
$a = 5$
God bless ....I hope the explanation is ... | {} |

# Is there a name for the square of a function plus the square of its Hilbert transform?
Given a real-valued analytic function $$f$$ defined on the whole real line, and its Hilbert transform $${\cal H}f$$, it seems that the quantity $$f(x)^2+{\cal H}f(x)^2$$ should have some kind of importance as an energy measure. It... | {} |
