Arguments

object

object of class GDINA

strict

whether a strict monotonicity is checked?

Value

a logical vector for each item or category indicating whether the monotonicity is violated (TRUE) or not (FALSE)

Examples

if (FALSE) { dat <- sim10GDINA$simdat Q <- sim10GDINA$simQ mod1 <- GDINA(dat = dat, Q = Q, model = "GDINA") check <- monocheck(mod1) check mod2 <- GDINA(dat = dat, Q = Q, model = "GDINA",mono.constraint = check) check2 <- monocheck(mod2) check2 }
