The response gains plot helps us answer the question: When we apply the model and select up until ntile X, what is the expected
Usage
mplot_response(
tag,
score,
multis = NA,
target = "auto",
splits = 10,
highlight = "auto",
caption = NA,
save = FALSE,
subdir = NA,
file_name = "viz_response.png",
quiet = FALSE
)Arguments
- tag
Vector. Real known label.
- score
Vector. Predicted value or model's result.
- multis
Data.frame. Containing columns with each category probability or score (only used when more than 2 categories coexist).
- target
Value. Which is your target positive value? If set to 'auto', the target with largest mean(score) will be selected. Change the value to overwrite. Only works for binary classes
- splits
Integer. Numer of quantiles to split the data
- highlight
Character or Integer. Which split should be used for the automatic conclussion in the plot? Set to "auto" for best value, "none" to turn off or the number of split.
- caption
Character. Caption to show in plot
- 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
- quiet
Boolean. Do not show message for auto target?
