computes a chi-square goodness-of-fit test for specified proportions. The chi-square goodness-of-fit test examines whether the children's hair color has a specified multinomial distribution for two ...

The chi-square test is a statistical hypothesis test that is used to compare observed and expected counts in a contingency table. Its uses include: tests for independence, tests for homogeneity, and ...

A statistical test that allows one to determine whether observed quantities of a specific characteristic differed from the expected value purely by chance.

Wald's method constructs test statistics having chi-squared limiting distributions from estimators having nonsingular multivariate normal limiting distributions, using the inverse of the covariance ...
