Re: [R] is there a package in R or functions to calculate odds/hasard ratio from spline regression

Hello, thank you for the answer. it's true i was'nt clear enough. the problem with glm()/gam or coxph() when the spline terms are used (specialy spline of 3rd degree) the calculated coefficients for the spline terms are difficult to interpret. for example for spline of degree=3 and 3 knots, there

Hello, I'm looking for a package or function, which calculate OR/HR from spline model regression. for example in SAS it exist some MACRO helping to do that easiely. i had make some research on the forum here and on the web but without any succes. thanks for the answers. Takiy -- Takiy
