Claim frequency for discrete risk factors in an insurance portfolio. For each level of the risk factor the claim frequency is equal to the ratio between the number of claims and the exposure.

Methods for insurance rating. It provides a data driven strategy for the construction of
insurance tariff classes. This strategy is based on the work by Antonio and Valdez (2012) <doi:10.1007/s10182-011-0152-7>.
The package also adds functionality showing additional lines for the reference
categories in the levels of the coefficients in the output of a generalized linear regression analysis.
In addition it implements a procedure determining the level of a factor with the largest exposure,
and thereafter changing the base level of the factor to this level.
