About this document

ANCOVA Power Analysis Techniques by name.syarif.hidayat is a document available to read on EtoBox.

This document summarizes a research article that proposes an exact approach for power and sample size calculations in analysis of covariance (ANCOVA) designs. The common method of applying ANOVA formulas with adjusted degrees of freedom and variance is intrinsically inexact because it violates the independence assumption required for ANOVA. The proposed method derives the exact power functions for Wald tests of general linear hypotheses under assumptions of specified or multivariate normal covariate values.
