[R] linear predictors and survreg function

2010-02-09 Thread carol white
Hi, I calculated the linear predictors derived from weibull model using ovarian data sets. I calculated the linear predictors as the sum of covariates weighted by the weibull coefficients and compared to the linear predictors generated by survreg function. Why are they different? note that the f
