ltvlms: Linear Time-Variant Logistic Models with a Shape Parameter

Evaluates and fits the Linear Time-Variant Logistic Model with Shape Parameter (LTVLMS) for dynamic growth processes. The model combines a linearly time-varying growth rate with a shape parameter for asymmetric trajectories and includes numerically stable prediction utilities. Methodological details are provided by Betrouni and Kernane (2026) "Linear Time-Varying Logistic Model With Shape Parameter for Dynamic Epidemic Modeling" <doi:10.1155/jama/4928447>.
