Description
Calculate the matrix W with all diagonal values as p(i).
Usage

Arguments
pi
is a list of predictions on each observation.
family
a character that determines the likelihood function.
If family is set to 'binomial', a likelihood for binary logistic regression is applied
If family is set to 'poisson', a likelihood for poisson regression is applied.
Details
It is a partial computation for Hessian Matrix (second derivative).
If the Hessian Matrix is H=XWX^T, the W matrix is W = P_i(1-P_i).
Value
the W matrix
