1. ### Lisrel not drawing fitted covariance matrices

Hi, I'm trying to get residual analysis in Lisrel 9.30 student edition but no matter where in "OU" line I put "RS" option, it doesn't output it. Even if I use option "ALL" for the output (and it does impact the output), there is no fitted covariance matrix in output. Was that removed in V9, is...
2. ### Testing scalar invariance of a second-order factor model in LISREL

I have a non-normal data for which I used satorra-bentler chi square. The problem I am facing is in testing the measurement invariance of a second-order factor model in lisrel. Unfortunately, the lisrel tutorial only shows examples of first order factor models and there is hardly any mention of...
3. ### LISREL-SIMPLIS 2nd Order MultiGroup Measurement invariance Testing

Hi Hi. I am using LISREL 8.8 (Simplis Commands) I am stuck in doing 2nd order Multigroup measurement Invariance - specifically i cannot get through the stage for equal intercepts (strong invariance/Measurement intercepts) I kept having errors and model does not converge. Hope some one...
4. ### [LISREL SIMPLIS] help with scalar invariance and calculating latent mean factors

Hello, I am conducting measurement equivalence on a two country sample (US and IN). I have established configural (baseline) and metric equivalence. However scalar invariance has not been established (the model change checks out but CFI change is less than .002). I examined the modification...
5. ### [LISREL] Looking for a guide to understand output and modify measurement models

Hi all, I am hoping someone can help me as I am so close to the end of my dissertation I can taste it! Okay, so my methodologist suggested that I create a Path Analysis model to test the relationships of my data obtained by community college students who were enrolled in online courses. Here...
6. ### [LISREL 8.7] syntax for a formative second order model

Hi: I am developing a scale, which is theoretically a first order reflective, and second order formative model. I have already analyzed the first order model and everything's ok, and results indicate that i should continue with a second order formative model. I do not know how to write the...
7. ### Easy question regarding SEM in lisrel

Hey all, I'm running a full SEM in lisrel and I'm having an issue. Below is the code. The issue is namely this: I specified Lambda Y as full and fixed, and then freed my 6 relevant parameters (1,1; 2,1; 3,2; 4,2; and 5;3). HOWEVER, Lisrel is only estimating LY(2,1) and LY(4,2) and the rest...
8. ### [LISREL] Is sequence of variables in Prelis important for making a model in SIMPLIS?

Hi everyone, I'm creating a structural equation model for my research by means of LISREL. Recently, i noticed that the order of my variables in my prelis file changed my entire model. I started by simply importing my spss file in Lisrel, updated the variable type and created a covariance...
9. ### Extreme Modification index

I am working on Confirmatory Factor Analysis in LISREL. Now, my first model reports an extremely high Modification Index (MI=2498,71) for one specific Lambda-X parameter. I decided NOT to free this parameter, but to free a parameter for associated measurement error between two items that...
10. ### [Lisrel] When including a control variable the solution doesnt converge

Hello, Im testing for the mediating effect and Lisrel works fine when only independent and dependent variables are included. The problem occurs when I include a control variable (TT) in SEM. I encounter the following warning: W_A_R_N_I_N_G: The solution has not converged after 820...
11. ### [Lisrel] Need help with Lisrel project

Hi, I am having trouble with my Lisrel Project. If there is someone who knows Lisrel, i would appreciate the help. I put my hypotheses, syntax and output in the attachments. Thanks in beforehand.
12. ### [LisRel] How can i add a polychoric correlation to my LisRel syntax?

Hi everyone, I'm creating a structural equation model for my research by means of LISREL. Recently, i noticed that the order of my variables in my prelis file changed my entire model. I started by simply importing my spss file in Lisrel, updated the variable type and created a covariance matrix...
13. ### LGC with Experimental Manipulations

Hey gang, first time posting. So, I have 9 time points of continuous learning data for 200ish people. I also have two manipulations (thus the 200 people are split into four groups, group size is unequal). I also collected several personality measures via questionnaires. I have a little bit...
14. ### [Lisrel] strange warning message (The path from .. to .. could not be interpreted)

Hi everyone! I’m doing Structural Equation Modeling using Lisrel. I basically want to do a path model involving both observed and latent variables at the same time. The model that I want to test is a mediation model, meaning that I want to test if X => M (Mediation variable, obs. variable) => Y...
15. ### LISREL syntax error

Hi all, I'm looking for help with my syntax testing invariance of means and intercepts across two groups. The data was teacher-supplied, so my problem is DEFINITELY somewhere in my syntax, which is posted below. I keep getting errors saying my phi matrix is not positive definite, and I have...
16. ### LISREL - Model does not converge, Matrix not positive definite

Hello, I have imported a large amount of data (250 observations, 15 variables) and defined a path diagram to develop SEM. But after building simplix syntax and running lisrel syntax, it says that the model does not converge and in the output file, following are the errors: Matrix to be...
17. ### Variance Extracted and Multicollinearity in Structural Equation Model

Hello, I am a new user here, and I am quite in need of help with regards to statistical problems. :) I really appreciate it if anyone can help me. I am currently doing a kind of "predicting user behaviour" research using Structural Equation Model (SEM). My software of choice is LISREL 8.80. I...
18. ### Testing for tau equivalence in a simple CFA model, based on correlation matrix

For an assignment we are provided with only a (polychoric) correlation matrix. One of the questions concerns the different measurement models that can be tested (congeneric, tau equivalent, parallel). My understanding of the course material would lead me to believe that analysing a...
