Tests and confidence intervals based on two normal samples with common variance
[pval, cimean, cisigma] = test2n(x,y,cl)
samples (column vectors)
confidence level for the confidence intervals (default 0.95).
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.
confidence interval for the difference of means.
confidence interval for the standard deviation. (Confidence intervals of the form [LeftLimit, PointEstimate, RightLimit]).
