dsld (version 0.2.2)

dsldConditDisparity: dsldConditDisparity

Description

Plots (estimated) mean Y against X, separately for each level of S, with restrictions condits. May reveal Simpson's Paradox-like differences not seen in merely plotting mean Y against X.

Usage

dsldConditDisparity(data, yName, sName, xName, condits = NULL,
    qeFtn = qeKNN, minS = 50, useLoess = TRUE)

Value

No value; plot.

Arguments

data

Data frame or equivalent.

yName

Name of predicted variable Y. Must be numeric or dichtomous R factor.

sName

Name of the sensitive variable S, an R factor

xName

Name of a numeric column for the X-axis.

condits

An R vector; each component is a character string for an R logical expression representing a desired condition involving names(data) other than S and Y.

qeFtn

qeML predictive function (not quoted; only default arguments will be used.)

minS

Minimum size for an S group to be retained in the analysis.

useLoess

If TRUE, do loess smoothing on the fitted regression values.

dsldConditDisparity(compas,"two_year_recid", "race", "age", 
    c("priors_count <= 4","decile_score>=6"), qeKNN)
