%description
Provides functions for estimation and data generation for several
piecewise lifetime distributions. The package implements the power
piecewise Weibull model, which includes the piecewise Rayleigh and
piecewise exponential models as special cases. See Feigl and Zelen (1965)
<doi:10.2307/2528247> for methodological details.
