Roorda11: Studies on Students' School Engagement and Achievement Reported by Roorda et al. (2011)

Description

The data set includes 45 studies on the influence of affective teacher-student relationships on students' school engagement and achievement reported by Roorda et al. (2011).

Usage

data(Roorda11)

Details

The variables are:

data

A list of 45 studies of correlation matrices. The variables are pos (positive teacher-student relations), neg (negative teacher-student relations), enga (student engagement), and achiev (student achievement).

n

A vector of sample sizes

SES

A vector of average socio-economic status (SES) of the samples

## Random-effects model: First stage analysis

## Prepare a regression model using create.mxMatrix()
A <- create.mxMatrix(c(0,0,0,0,
                       0,0,0,0,
                       "0.1*b31","0.1*b32",0,0,

                     name = "A", as.mxMatrix = FALSE)

## This step is not necessary but it is useful for inspecting the model.
