##---- Should be DIRECTLY executable !! ---- ##-- ==> Define data, use random, ##-- or do help(data=index) for the standard data sets. ## The function is currently defined as function(dat, params){ raschO <- function(b,theta){ 1 - (1 / (1 + exp(outer(theta,b,'-')))) } theta <- apply(dat, 1, theta.max, params) p <- raschO(as.vector(params), theta) z2 <-((dat - p)/ sqrt(p * (1- p)))^2 v <- sqrt(p * (1- p))^2 IF <- colSums(z2*v) / colSums(v) OF <- colMeans(z2) data.frame(IF,OF) }
