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.
