Stixbox Function test2n - Tests and confidence intervals based on two normal samples with common variance
Calling Sequence
- [pval, cimean, cisigma] = test2n(x,y,cl)
Parameters
- x,y
: samples (column vectors)
- cl
: confidence level for the confidence intervals (default 0.95).
- pval
: probability that Student statistic based on x and y is as far from 0 as it is actually, or further away under hypothesis that theoretical means are equal.
- cimean
: confidence interval for the difference of means.
- cisigma
: confidence interval for the standard deviation. (Confidence intervals of the form [LeftLimit, PointEstimate, RightLimit]).
Description
Tests and confidence intervals based on two normal samples with common
variance.
