Hi, all,

In the Cox proportional model, if the hazard function is 

lambda_i (t) = W_i * lambda_0 (t) * exp(beta*X_i),

which means that there is a weight for the hazard function of individual i. 
Does 
anybody know if there is a function available in Splus to estimate the 
covariate 
coefficients? Thank you all.
