Webcredibility weighted rate change indications were calculated: Credibility weighted rate change = Zi x Ri + (1 − Zi) x (+2.0 %) . indication for territory i The credibility weights Zi were calculated from the formula Zi = ni / (ni + K ) where ni was the number of insured vehicles in the territory during the three-year data collection period. Webcredibility theory in a multivariate context The calculation of the conditional MSEP for the predictor of the ultimate claim for a whole portfolio of several correlated run-off portfolios is more sophis-ticated than for only one run-off portfolio. Holmberg (1994) was probably the first one to investigate the WebJun 5, 2012 · Bühlmann credibility theory sets the problem in a rigorous statistical framework of optimal prediction, using the least mean squared error criterion. It is flexible enough to incorporate various distributional assumptions of loss variables. csv data with date
