Where are the functions fpval and chi2pval in the builtin function canoncor

I am using the standard Matlab function canoncorr.m to calculate canonical correlations between two large data sets. However, I get error messages on lines 145 and 149. This error also appears with basic random 3x9 matrices for both x and y. line 145: stats.pF = fpval(stats.F, stats.df1, stats.df2); line 149…

Gaussian mixture model sometimes seems to fit very badly

In the following code, I fit a gaussian mixture model (GMM) to some randomly sampled data. I do this twice. Each time, the data represent two well separated gaussians, the only difference being the seed I use for the random number generator. N = 100000; EFFECT_SIZE = 5; seedList =…
