Allow Predictive Tools to Model Mean (No Predictors)

[Kenda]

Sometimes, as a sanity check, I would like to be able to model only the mean of my data set, i.e. I would like to use a predictive tool with no predictors included. The result would be a model with only an intercept, and this value would be the mean of the target variable. This would not be an important feature for final models, of course, but when starting to look at a data set and build up a model, it can be useful to first ensure the model is producing the expected output in the simplest case. 

Note, this can be achieved when just one predictor is included, but it takes some math (see below), so it would be nice to be able to have this as a built-in option.
