WebIn this paper the rank transformation approach to analysis of covariance is presented and examined. Comparisons are made with the rank transformation procedure given by Quade (1967, Journal of the American Statistical Association 62, 1187-1200), and some 'standard' data sets are used to compare the results of these two procedures.

ANCOVA stands for ‘Analysis of covariance’, and it combines the methods used in ANOVA with linear regressionon a number of different levels . The resulting output shows the effect of the independent variable after the effects of the covariates have been removed/accounted for.
