Mosaic displays is the graphical display of the standardized residuals from the fitting a log-linear model to a contingency table in which the colour and outline of the mosaic's 'tiles' are used to indicate size and the direction of the residuals with area of the 'tiles' being proportional to corresponding number of cases. An instance is shown in the Figure; here the display represents the residuals from fitting an independence model to counts of the hair and eye colour from men and women. The plot indicates that there are more number of blue-eyed blond females than the expected under independence and too few brown-eyed blond females.
a. Explain the meaning of the word non-orthogonal. b. What condition(s) must exist for non-orthogonality to occur? Be specific.
