AdjR2: Calculates adjusted R-Squared statistic

In poliscidata: Datasets and Functions Featured in Pollock and Edwards, an R Companion to Essentials of Political Analysis, Second Edition

Description

Calculates adjusted R-Squared statistic based on user-defined inputs. This function can be used after estimating a model that does not report adjusted R-Squared statistic. For svyglm model fit statistics, see fit.svyglm function documentation.

Usage

AdjR2(tdf, null.dev, resid.dev, k)

Arguments

tdf	The total degrees of freedom
null.dev	The null deviance or total sum of squares
resid.dev	The residual deviance or error sum of squares
k	The number of parameters used (to reduce deviance)

Value

Returns an adjusted R-Squared statistic, a numeric value between 0 and 1

Examples

   AdjR2(200, 1500, 1100, 5)
   
   AdjR2(tdf=200, null.dev=1500, resid.dev=1100, k=5)

Example output

[1] 0.2478632
[1] 0.2478632
