Alternative parameterization in Parametric Survival Modeling

GregMcMahon

Hi everyone,

 

Once again this will likely be a stupid question and blatantly obvious, but how come when I run a Parametric Survival Model, I only get the alternative parameterization values if I choose a Weibull model?

 

Many thanks and hope everyone is well,

Best.

JMP estimates the alternative parameters because that form of the model is more numerically stable.
