Plot Histogram of Gammas
Description
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.
Usage
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 |
Value
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")
