This depends on the model that you are using.</P> <P>What are your settings for the model?</P> <P>Could you give us an example of your parameter estimates and one line of data?</P> <P>Thx,</P> <P>Greg</P> Fri, 22 Jul 2016 13:05:30 GMT gergely_batho 2016-07-22T13:05:30Z https://communities.sas.com/t5/SAS-Data-Science/Ratemaking-Parameters-Result/m-p/286350#M4251 <P>Helo all;</P><P>&nbsp;</P><P>After runing the Ratemaking node of SAS MINER one of the resalts is Parameters Estimates, it give us the parameters for each input variable in our model. I know that to calculate the rate for a tarif cel we must calculate the exponential of the sum of the parameters in the cel, but whenever i do that my values are not the same to the predicted values given by the score node.</P><P>Please someone help me undertand it.&nbsp;</P> Fri, 22 Jul 2016 10:22:13 GMT https://communities.sas.com/t5/SAS-Data-Science/Ratemaking-Parameters-Result/m-p/286350#M4251 Uriel 2016-07-22T10:22:13Z https://communities.sas.com/t5/SAS-Data-Science/Ratemaking-Parameters-Result/m-p/286370#M4252 <P>Hi,</P> <P>Yes: first you calculate the weighted sum, and then exponentiate it... or you do something else.
