%description
Performs survival analysis using general non-linear models. Risk models
can be the sum or product of terms. Each term is the product of
exponential/linear functions of covariates. Additionally sub-terms can be
defined as a sum of exponential, linear threshold, and step functions. Cox
Proportional hazards

regression are supported. This work was sponsored by NASA Grant
80NSSC19M0161 through a subcontract from the National Council on Radiation
Protection and Measurements (NCRP). The computing for this project was
performed on the Beocat Research Cluster at Kansas State University, which
is funded in part by NSF grants CNS-1006860, EPS-1006860, EPS-0919443,
