Publisher review:Power Analysis for T-tests computes power and required samples size for t-tests. The main function, TPOWER, will compute the power of a t-test given an effect size (d), sample size (N), and alpha. By giving N as an array the program can be used to plan sample size for an experiment.
By setting the "PLOT" parameter to 1 the function calls plotpowfun, which plots the array N against power. By providing a desired power level, DESPWR, the program will also determine the minimum sample size needed to reach the desired power. Requirements: · MATLAB Release: R14 · Statistics Toolbox
