The fathers were selected from three groups: (a) fathers of a child with no disabilities; (b) fathers with a physically disabled child; (c) fathers with a mentally disabled child.

Format

A data frame with 60 observations on the following 4 variables.

group

a factor with levels Normal Physical Disability Mental Disability

caring

caretaking responsibilities, a numeric vector

emotion

emotional support provided to the child, a numeric vector

play

recreational time spent with the child, a numeric vector

Details

The scores on the response variables are discrete.

# fit the MLM
