Dear all, how can i do the calculate the C-statistics 95% confidences interval for the cox regression model. Thanks very much for your any help. Paaveenthan _________________________________________________________________ [[elided Hotmail spam]] [[alternative HTML version deleted]]

I am fittting a linner regression with constrained parameters, saying, all parameters are non-negative and sum up to 1. I have searched historical R-help and found that this can be done by solve.QP from the quadprog package. I need to assess the significance of the coefficient estimates, but there is no standard error of the coefficient estimates in the output. So I can not compute the p-value.
