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: No special requirements
Platforms: Matlab
Keyword: Calls Desired Level Needed Plotpowfun Plots Providing Reach
