aiPuxComposite: Estimate ai and average criterion scores for majority and minority groups.

Description

Estimate ai and average criterion scores for majority and minority groups.

Usage

aiPuxComposite(r_mat, y_col, x_col, dX, dY, wt_x, wt_y, sr, pct_minority)

Arguments

r_mat

Super correlation matrix between the predictors and criteria. This argument assumes that the predictors come first in the matrix.

y_col

A vector of columns representing criterion variables.

x_col

A vector of columns representing predictor variables.

dX

A vector of d values for the predictors. These d values are expected to have been computed in the direction of Majority - Minority.

dY

A vector of d values for the criteria These d values are expected to have been computed in the direction of Majority - Minority.

wt_x

Weights for the predictors to form the overall composite predictor.

wt_y

Weights for the criteria to form the overall composite criterion.

sr

The percentage of the applicant population who are selected.

pct_minority

The percentage of the applicant population who are part of a given minority group.

Value

• AIAdverse Impact
• Overeall_srThe overall selection ratio set by the user
• Majority_srMajority Selection Rate
• Minority_srMinority Selection Rate
• Majority_StandardizedPredicted composite criterion score relative to the majority population
• Global_StandardizedPredicted composite criterion score relative to the overall population
