Is the theoretical value of the square multiple correlation coefficient. Exploratory data analysis and working with the regression diagnostics is an important aspect of ANCOVA.

The effect size is then multiplied by f 1 1 ρ where ρ.
And sample size we propose two methods to plan the sample size for an ANCOVA or ANOVA study so that a sufficiently narrow CI for the population standardized or unstandardized contrast of interest will be obtained. We present a method for the sample size calculation when ANCOVA is used. The effect size is then multiplied by f 1 1 ρ where ρ. If the correlation between the outcome measured at baseline and at follow-up is rho ANCOVA comparing groups of 1-rho2n subjects has the same power as t-test comparing groups of n subjects.
