Estimating The Effect Of Statutory Changes On Insured Casualty Losses Using Generalized Indicator Variables, Ruy A. Cardoso

Using indicator variables and dummy variables allows for quantification of the effect of such discontinuities. Three examples from private passenger automobile insurance are presented to illustrate how these variables can be used.
