How can I compute the probability that a set has normal distribution with zero mean
in [Matlab]

From: Oleg on 27 Jul 2010 14:22 I have two data tables as a result of two similar experiments. I want to check and, if possibly, to compare the chances whether residuals in rows have normal distribution with zero mean. The problem is that kstest compares with standart normal distribution (fixed mean and SD), and lillietest is nonparametric test. Thanks for answers!

You can input the CDF into kstest() that you want (N(0,\sigma^2)) as a ProbDist object. See >> doc ProbDistUnivParam or 2.) You can standardize the residuals. Wayne
