Package segmented is aimed to estimate linear and generalized linear models
having one or more segmented relationships in the linear predictor. Estimates of the slopes and
of the possibly multiple breakpoints are provided. The package includes testing/estimating
functions and methods to print, summarize and plot the results.References
