gamma_histogram function

Plot Histogram of Gammas

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.

gamma_histogram(fe_results, bins = 100, caption = "")

Arguments

• fe_results: The result of fe_search or full_embedding_search. A matrix containing a column labeled Gamma, of Numeric Gamma values. It also contains an integer column of masks, but that is not used by this function.
• bins: Numeric, number of bins in the histogram
• caption: Character string caption for the plot

Returns

a ggplot object, a histogram showing the distribution of Gamma values full embedding search output

Examples

e6 <- embed(mgls, 7)
t <- e6[ ,1]
p <- e6[ ,2:7]
full_search <- fe_search(predictors = p, target = t)
gamma_histogram(full_search, caption = "my data")
