Father Parenting Competence

Description

The data, from an exercise given by Meyers et al. (2006) relates to 60 fathers assessed on three subscales of a Perceived Parenting Competence Scale. 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.

Examples

data(Parenting)
require(car)

# fit the MLM
parenting.mod <- lm(cbind(caring, emotion, play) ~ group, data=Parenting)
car::Anova(parenting.mod)

# Box's M test
boxM(parenting.mod)
plot(boxM(parenting.mod))

parenting.mod <- lm(cbind(caring, emotion, play) ~ group, data=Parenting)
car::Anova(parenting.mod)
# test contrasts
print(linearHypothesis(parenting.mod, "group1"), SSP=FALSE)
print(linearHypothesis(parenting.mod, "group2"), SSP=FALSE)


heplot(parenting.mod)
# display tests of contrasts
hyp <- list("N:MP" = "group1", "M:P" = "group2")
heplot(parenting.mod, hypotheses=hyp)

# make a prettier plot
heplot(parenting.mod, hypotheses=hyp, asp=1,
       fill=TRUE, fill.alpha=c(0.3,0.1), 
       col=c("red", "blue"),

       cex=1.4, cex.lab=1.4, lwd=3)

pairs(parenting.mod, fill=TRUE, fill.alpha=c(0.3, 0.1))
