Gaussian ordinate many standard deviations out

sigma f(n sigma) = e^(-n^2/2)/sqrt(2 pi), independent of sigma. The default n = 20 is the book's 1e-87 illustration.

Usage

GaussTail(n_sigmas = 20, sigma = 1)

Arguments

n_sigmas

how many standard deviations out to evaluate.

sigma

standard deviation, > 0.

Value

list(n_sigmas, area_fraction).
