Package 'srpi'

Title: Standardized Ranking Performance Index for Model Selection
Description: Flexible implementation of the Standardized Ranking Performance Index (sRPI) for model selection based on multiple evaluation criteria. The package combines multiple statistical measures into a single index to provide an objective and robust ranking of models across calibration, validation, and combined scenarios. It supports evaluation of statistical, machine learning, and other predictive models using user-defined performance criteria. For more details see Aschonitis et al. (2019) <doi:10.1016/j.envsoft.2019.01.005> and Singh et al. (2023) <doi:10.1016/j.ecoinf.2022.101933>.

Example calibration dataset

Description

Example dataset used for sRPI calculation

Usage

cal_example

Format

A data frame with 12 rows and 5 variables

Combine sRPI

Description

Combine sRPI

Usage

combine_srpi(cal, val)

Arguments

cal

Calibration results
val

Validation results

Value

A data frame containing Model, calibration sRPI, validation sRPI, combined sRPI, and final ranking of models.

Examples

criteria <- c("R2","dindex","MBE","RMSE")
type <- c("max","max","min","min")
cal_res <- srpi(cal_example, criteria, type)
val_res <- srpi(val_example, criteria, type)
combine_srpi(cal_res, val_res)

Plot sRPI

Description

Value

No return value. This function generates a plot.

Examples

data(cal_example)
data(val_example)
criteria <- c("R2","dindex","MBE","RMSE")
