Abstract: The invention provides a method and system for determining rates of insurance for travelers based on certain risk parameters. Insurance rates are computed using factor relativities derived from insured data and parameters for several different insurance coverages. Factor relativities are computed through an iterative process using a minimum bias procedure according to each coverage. Parameters are evaluated simultaneously for each coverage to eliminate cross bias from one parameter to another. Once factor relativities are calculated, the system and method allows for a consumer to request a rate on an insurance coverage. The system and method provides the rate using the factor relativities for the requested coverage. The method and system also provides insurance rates to additional or upgraded insurance coverages based on consumer preferences.
