gamma_histogram

Produces a histogram showing the distribution in a population of Gamma
values, used to examine the result of a full embedding search. Pass the result
of fe_search() to this function to look for structure in the predictors.
For example, it this histogram is bimodal, there is probably one input variable
which is absolutely required for a good predictive function, so the histogram
divides into the subset containing that variable, and the others that don't.

Finds causal connections in precision data, finds lags and embeddings in
time series, guides training of neural networks and other smooth models, evaluates
their performance, gives a mathematically grounded answer to the over-training
problem. Smooth regression is based on the Gamma test, which measures smoothness
in a multivariate relationship. Causal relations are smooth, noise is not.
'sr' includes the Gamma test and search techniques that use it.
