Thank you very much C.Ret. You made it clear to me about the use of weights, and this satisfied me. However, I would need an iterative program for calculating Cox's (multiple) regression in the survival analysis. The HP PRIME calculator is very powerful and gives, for example, the possibility to program a "classic" multiple regression, thanks to the powerful matrix calculation and the LSQ command. The situation becomes more complex when the calculation of the Cox regression "demands" an iterative numerical approach. The HP PRIME calculator gives you the ability to solve optimization problems with the "simplex_reduce" command, but it doesn't give you the ability (at least I think) to calculate Cox regression coefficients. Since I am not an expert programmer, I have searched the solution of my problem on the web, and a "partial" answer to my problem was given to me by "rawi". I cordially greet you, Roberto. |
