Examples

data(Cement)
Cement$X1 <- cut(Cement$X1, 3)
Cement$X2 <- cut(Cement$X2, 2)

fm1 <- glm(formula = y ~ X + X1 + X2 * X3, data = Cement)
fm2 <- update(fm1, . ~ . - X - X1)
fm3 <- update(fm1, . ~ . - X2 - X3)

# ranked with default AICc
mod.sel(fm1, fm2, fm3)

# ranked with BIC
mod.sel(fm1, fm2, fm3, rank=AIC, rank.args=alist(k=log(nobs(x))))
