This function lets us split and compare quantiles on a given prediction to compare different categorical values vs scores grouped by equal sized buckets.
Usage
mplot_splits(
tag,
score,
splits = 5,
subtitle = NA,
model_name = NA,
save = FALSE,
subdir = NA,
file_name = "viz_splits.png"
)Arguments
- tag
Vector. Real known label.
- score
Vector. Predicted value or model's result.
- splits
Integer. Number of separations to plot
- subtitle
Character. Subtitle to show in plot
- model_name
Character. Model's name
- save
Boolean. Save output plot into working directory
- subdir
Character. Sub directory on which you wish to save the plot
- file_name
Character. File name as you wish to save the plot
