I need help to plot continuous latent variable interactions. I used LMS in Mplus to find the interaction: ANALYSIS: type = missing; TYPE = RANDOM; ALGORITHM = INTEGRATION; Model: m1 by a1 a2 a3 a4; m2 by a5 a6 a7 a8; m3 by a9 a10 a11 a12; m4 by a13 a14 a15 a16; m5 by a17 a18 a19 a20; m1xiv | m1 XWITH iv; dv on iv (a1); dv on m1xiv (a3); dv on covariates; dv on m1 m2 m3 m4 m5; And created constraints to probe the interaction: MODEL CONSTRAINT: NEW(ss1-ss10); ss1=a1+a3*1; ss2=a1+a3*2; ss3=a1+a3*3; ss4=a1+a3*4; ss5=a1+a3*5; ss6=a1+a3*10; ss7=a1+a3*15; ss8=a1+a3*20; ss9=a1+a3*25; ss10=a1+a3*30; But, now, how do I plot the interaction? Where do I find this information? |

Take a look at how the interaction is expressed on slide 164 - for the Topic 3 handout of 5/17/2010. |

How do I find the mean of the interaction (z) and plus or minus one standard deviation around the mean of z? |

Correction: How do I find the mean of the moderator (z) and plus or minus one standard deviation around the mean of z? |
|
|
For an observed moderator, do a Type=Basic run. |

The moderator is latent. Is there a way to find the mean, SD for a latent moderator? |

See TECH4. |

I tried TECH4 and received the following message: *** WARNING in OUTPUT command TECH4 option is not available for TYPE=RANDOM. Request for TECH4 is ignored. |
