News from the IBM SPSS Community

[Jon K Peck]

A pair of new extension commands for Statistics have been posted to the Extension Commands collection on the SPSS Community website (www.ibm.com/developerworks/spssdevcentral)

STATS GBM estimates generalized boosted regression models including regular regression, logistic, multinomial, poisson, and quantile regression among others.
STATS GBMPRED uses the estimates from STATS GBM to calculate predicted values for new data.

These procedures use the R gbm package and require the R Essentials.  They were developed using Statistics V21 but should work with version 18 or newer.

I am calling these beta versions as there are many features that are difficult to test comprehensively in combination.  Please report any bugs or comments to me.
