NCT: Stata modules related to the noncentral t distribution

Statistical Software Components from Boston College Department of Economics

Abstract: nct is a package of programs, all related to the noncentral t distribution. Each one-sided program computes a missing parameter given the other parameters such that P(t<=t'| delta, df) = p. The two-sided programs yield two-sided values from a noncentral t, defined such that P(|t|<=t'| delta, df) = 1 - p. The programs are: nctprob -- Cumulative non-central t probabilities, p, nctinv -- Inverse cumulative non-central t values, t', nctncp -- Noncentrality parameter of the non-central t, delta, nctn -- Sample size for the cumulative non-central t, df + 1, nct2 -- 2-sided non-central t probabilities, p, and nct2inv -- Inverse 2-sided non-central t values, |t'|.
