Arguments

X

Design matrix of the logistic model considered.

beta

##---- 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 (X, beta, intercept = 0) 
{
    prob <- 1/(1 + exp(-(X %*% beta + intercept)))
    return(prob)
  }
