install.packages("pammtools")pammtools facilitates the estimation of Piece-wise exponential
Additive Mixed Models (PAMMs) for time-to-event data. PAMMs can be
represented as generalized additive models and can therefore be
estimated using GAM software (e.g. mgcv), which, compared to other
packages for survival analysis, often offers more flexibility w.r.t. to
the specification of covariate effects (e.g. non-linear, time-varying
effects, cumulative effects, etc.).
