Logistic regression newton raphson
Witrynamation is carried out with either the Fisher-scoring algorithm or the Newton-Raphson algorithm. You can specify starting values for the parameter estimates. The logit link function in the logistic regression models can be replaced by the probit function or the complementary log-log function.
