%description
Fits actuarial claim severity distributions to ground-up loss data while
accounting for deductible truncation, policy-limit censoring, observation
weights, optional severity scaling variables, and fixed parameters.
Supports single-family and spliced body-tail models, candidate-model
comparison, limited expected values, loss elimination ratios, increased
limits factors, deductible and limit rating factors, valuation or
depreciation adjustments, simulation, diagnostics, and uncertainty
estimation. The package is designed for property and casualty actuarial
applications in which analysts fit ground-up severity and translate the
fitted distribution into pricing factors for limits, deductibles, and
valuation provisions. For background on statistical severity modeling, see
Klugman, Panjer, and Willmot (2019, ISBN:9781119523789), "Loss Models:
From Data to Decisions", 5th edition.
