cdf.test(model, covariate, test)
where model is a fitted model ( of class "mppm") and covariate is either a function(x,y) making
it possible to compute the value of the covariate at any lo cation (x,y); a pixel im age containing the
covariate values; a list of functions, one for each row of the hyper frame of original data; a list of
pixel images, one for each row of the hyperframe of or iginal data; o r a hyperframe with one column
containing either functions or pixel images. Again the argument test is either "ks", "cvm", or
