We show in this post that an elegant continued fraction for ${e}$ can be found using derangement numbers. Recall from last week’s post that we call any permutation of the elements of a set an arrangement. A derangement is an arrangement for which every element is moved fr... | {} |
# Extremal Rays of a Cone
Can I use Sage to compute the subspace of a vector space that lies in non-negative real Euclidean space?
For example,
If I compute the nullspace of the matrix,
A =
[ [ 1 0 0 -1 0]
[-1 1 0 0 1]
[ 0 -1 1 0 0]
[ 0 0 -1 1 -1] ]
I get,
[1,1,1,1,0],[0,−1,−1,0,1]
as basis. Now I would like to res... | {} |
## 6.3 The StructTS function
The StructTS function in the stats package in R will also fit the stochastic level model:
fit.sts <- StructTS(dat, type = "level")
fit.sts
Call:
StructTS(x = dat, type = "level")
Variances:
level epsilon

# Squarefree products of a class of primes
Numbers which are the sum of two squares are the product of a square and a collection of distinct primes which are 1 or 2 mod 4.
