stdcoef: Standardized Regression Coefficients

Description

Computes standardized ("beta") regression coefficients for a fitted lm or mlm object, i.e. the coefficients that would result from fitting the same model with all numeric variables rescaled to mean 0, SD 1.

For an "mlm" object, standardization follows stdmodel()'s convention: the response(s) and numeric predictors are standardized; factor predictors are left raw.

Usage

stdcoef(object, ...)
# S3 method for lm
stdcoef(object, ...)
# S3 method for mlm
stdcoef(object, ...)

Value

For an "lm" object, a named numeric vector of standardized coefficients (intercept excluded). For an "mlm" object, a numeric matrix of standardized coefficients (parameters x responses, intercept row excluded).

Arguments

object

A fitted "lm" or "mlm" object

...

Additional arguments. Not used.

Examples

data(Prestige, package = "carData")
prestige.mod <- lm(prestige ~ income + education, data = Prestige)
stdcoef(prestige.mod)

rohwer.mod <- lm(cbind(SAT, PPVT, Raven) ~ SES + n + s + ns + na + ss, data = Rohwer)
stdcoef(rohwer.mod)
