coef.glc: Extract 'glc' or 'gcjc' coefficients

Description

Extracts the coefficients from the model object glc, glcStruct, or gcjc.

Usage

# S3 method for glc
coef(object, …)
# S3 method for glcStruct
coef(object, …)
# S3 method for gcjc
coef(object, …)

Arguments

object

object of class glc or glcStruct

…

further arguments

Details

Both the object glc and glcStruct contain the parameters for the decision boundary in the form: $$ a_1x_1 + a_2x_2 \ldots a_nx_n + b = 0 $$

This function transforms and returns the coefficients of the function solved with respect the \(x_n\).

For the object gcjc, a list of two coefficients (Intercepts) are returned.

Examples

# NOT RUN {
data(subjdemo_2d)
fit.2dl <- glc(response ~ x + y, data=subjdemo_2d,
    category=subjdemo_2d$category, zlimit=7)
plot(fit.2dl, fitdb=FALSE)
abline(coef(fit.2dl), col = "red")
abline(coef(fit.2dl$initpar))

fit.1dx <- update(fit.2dl, . ~ . -y)
abline(v=coef(fit.1dx), col="green")

fit.1dy <- update(fit.2dl, . ~ . -x)
abline(h=coef(fit.1dy), col="blue")
# }
