...d by means of a formula object and data is extracted from a matrix or data frame. There are special methods of print(), summary() for objects of class "cm". Credibility premiums are computed using a method of predict(); see below. For simple B?hlmann and B?hlmann-Straub models, bstraub() remains simpler to use and faster. o Function bstraub() now returns an object of class "bstraub" for which there exist print and summary methods. The function no longer computes the credibility premiums; see the "Deprecated, defunct or no backward compatibility" below...

...regression models in cm() has changed: one should now provide the regression model as a formula and the regressors in a separate matrix or data frame. o Due to above change, predict.cm() now expects 'newdata' to be a data frame as for stats:::predict.lm(). o Function bstraub() is no longer exported. Users are expected to use cm() as interface instead. BUG FIXES o Functions r<foo>() are now more consistent in warning when NA's (specifically NaN's) are generated (as per the change in R 2.7.0). o frequency.portfolio was wrongly counting NA...

...uitive. The fix has no effect when using the default weights. o The empirical step function returned by the "recursive" and "convolution" methods of aggregateDist() now correctly returns 1 when evaluated past its largest knot. DEPRECATED o Direct usage of bstraub() is now deprecated in favor of cm(). The function will remain in the package since it is used internally by cm(), but it will not be exported in future releases of the package. The current format of the results is also deprecated. --- Vincent Goulet, Associate Professor ?col...
