Is there an R function that I can use to calculate the p-value from the Z statistics computed for the relationship between chance and observed proportions in predictions. More sprcifically I am refering to proportional chance criteria (Cpro). Details are in Huberty's book on Applied discriminant analysis, unfortunately our library has misplaced the book. I got some details from the following page http://marketing.byu.edu/htmlpages/tutorials/discriminant.htm but I still need to compute the p-val from their Z-statistic. Thanks ../Murli
