Takes user input generated from SEMM software such as Mplus (Muthen & Muthen, 2007),
Mx (Neale, Boker, Xie & Maes, 2004) or MECOSA (Arminger, Wittenberg, & Schepers, 1996)
in Gauss and generates model predicted data for processing in graphing functions
plotSEMM_contour
and plotSEMM_probability
. Reterns a data.frame
to be passed to other functions in the package.
1 | plotSEMM_setup(pi, alpha1, alpha2, beta21, psi11, psi22, points = 50)
|
pi |
Vector: K marginal class probabilities. |
alpha1 |
Vector: K means of the latent predictor. |
alpha2 |
Vector: K inercepts slopes from the within-class regression of the latent outcome on the latent predictor. |
beta21 |
Vector: K slopes from the within-class regression of the latent outcome on the latent predictor. |
psi11 |
Vector: K within-class variances of the latent predictor. |
psi22 |
Vector: K within-class variances of the latent outcome. |
points |
number of points to use. Default is 50 |
All the parameter estimates required by the arguments are generated from software with the capability of estimating SEMMs.
