"Analysis of covariance is a combination of regression and analysis of variance. The prime advantage of using the Ancova model is to reduce the variability of the random error that is associated with covariates to obtain more precise estimates and powerful tests. The aim of thesis is to estimate the analysis of covariance model when the error distribution is non-normal."
