Back-transform Residuals to Proportion Scale

Source: R/transformation_helpers.R
backtransform_residuals.Rd

Transforms residuals from probit scale back to the original proportion scale. Computes the response on probit scale, then calculates residuals and standard errors on the proportion scale.

Usage

backtransform_residuals(df)

Arguments

df

Data frame containing columns:

  • level: Predicted value on probit scale

  • residual: Residual on probit scale

  • scale: Standard error on probit scale

Value

Data frame with added columns:

  • response: Observed value on probit scale (level + residual)

  • residual_ori: Residual on proportion scale

  • scale_ori: Standard error on proportion scale
