Evaluate the performance of different (binary) classification models

Description

Evaluate the performance of different (binary) classification models

Usage

evalbin(
  dataset,
  pred,
  rvar,
  lev = "",
  qnt = 10,
  cost = 1,
  margin = 2,
  scale = 1,
  train = "All",
  data_filter = "",
  arr = "",
  rows = NULL,
  envir = parent.frame()
)

Arguments

dataset	Dataset
pred	Predictions or predictors
rvar	Response variable
lev	The level in the response variable defined as success
qnt	Number of bins to create
cost	Cost for each connection (e.g., email or mailing)
margin	Margin on each customer purchase
scale	Scaling factor to apply to calculations
train	Use data from training ("Training"), test ("Test"), both ("Both"), or all data ("All") to evaluate model evalbin
data_filter	Expression entered in, e.g., Data > View to filter the dataset in Radiant. The expression should be a string (e.g., "price > 10000")
arr	Expression to arrange (sort) the data on (e.g., "color, desc(price)")
rows	Rows to select from the specified dataset
envir	Environment to extract data from

Details

Evaluate different (binary) classification models based on predictions. See https://radiant-rstats.github.io/docs/model/evalbin.html for an example in Radiant
