NettetA special class of nonlinear models, called generalized linear models, uses linear methods. Recall that linear models have these characteristics: At each set of values for the predictors, the response has a normal distribution with mean μ. A coefficient vector b defines a linear combination Xb of the predictors X. NettetPredict whether students got a B or above on their last exam by using lassoglm. Load the examgrades data set.

The fact that the transformation would also make the conditional distribution less skew would be a bonus, rather than a requirement.
