Lisrel 8.8 is not only limited to SEM, but also includes other statistical applications, such as:


  • PRELIS: an application for data manipulation, data transformation, computing moment matrices, linear regression, logistic regression, and exploratory factor analysis.



  • MULTILEV: an application that fits multilevel linear and nonlinear models to multilevel data from random and complex survey designs.



  • SURVEYGLIM: an application that fits generalized linear models to data from simple random and complex survey designs.



  • MAPGLIM: an application that implements maximum a priori method to fit generalized linear models to multilevel data.



Lisrel 8.8 can handle various types of data and models, such as:


  • Complete and incomplete simple random sample data on categorical and continuous variables.



  • Complete and incomplete complex survey data on categorical and continuous variables.



  • Confirmatory factor analysis models.



  • Structural regression models.

How to Use Lisrel 8.8 for Data Analysis?




Once you have installed Lisrel 8.8 full version, you can start using it for your data analysis. You can either use the graphical mode or the syntax mode to specify your model and data. The graphical mode allows you to draw your model using icons and arrows, while the syntax mode allows you to write your model using equations and commands. You can also switch between the two modes at any time.


To use the graphical mode, you need to:


<ol


  • Click on the File menu and select New Project.



  • Enter a name for your project and select a folder to save it.



  • Click on the Model menu and select New Model.



  • Select the type of model you want to create, such as confirmatory factor analysis, structural regression, multilevel, etc.



  • Use the icons on the toolbar to draw your model. You can add variables, latent variables, errors, covariances, paths, etc. You can also edit the labels, values, and constraints of each element.



  • Click on the Data menu and select Import Data.



  • Select the type and format of your data file, such as ASCII, SPSS, SAS, etc.



  • Browse and select your data file and click Open.



  • Check if your data are correctly imported and matched with your model variables.



  • Click on the Analysis menu and select Estimate Model.



  • Select the estimation method and options you want to use, such as maximum likelihood, weighted least squares, robust standard errors, etc.



  • Click OK and wait for the analysis to finish.



  • Click on the Output menu and select View Output.



  • Review the output tables and graphs that show the results of your analysis. You can see the parameter estimates, standard errors, fit indices, residuals, modification indices, etc.



To use the syntax mode, you need to:


<ol


  • Click on the File menu and select New Project.



  • Enter a name for your project and select a folder to save it.



  • Click on the Model menu and select New Model.



  • Select the Syntax Editor option and click OK.



  • Write your model using the Lisrel syntax. You can use the help menu or the manual to learn the syntax rules and commands. You can also use the examples and tutorials to see how to write different types of models.



  • Click on the Data menu and select Import Data.



  • Select the type and format of your data file, such as ASCII, SPSS, SAS, etc.



  • Browse and select your data file and click Open.



  • Check if your data are correctly imported and matched with your model variables.



  • Click on the Analysis menu and select Estimate Model.



  • Select the estimation method and options you want to use, such as maximum likelihood, weighted least squares, robust standard errors, etc.



  • Click OK and wait for the analysis to finish.



  • Click on the Output menu and select View Output.



  • Review the output tables and graphs that show the results of your analysis. You can see the parameter estimates, standard errors, fit indices, residuals, modification indices, etc.



Lisrel 8.8 also allows you to switch between the graphical mode and the syntax mode at any time. You can use the Convert option on the Model menu to convert your model from graphical to syntax or vice versa. You can also use the Edit option on the Model menu to edit your model in either mode. This way, you can take advantage of both modes depending on your preference and convenience.


How to Choose the Output Options in Lisrel 8.8?




Lisrel 8.8 provides various output options that you can choose from depending on your needs and interests. You can select the output options before or after estimating your model. You can also change the output options at any time and rerun your analysis without affecting your model or data.


To choose the output options in Lisrel 8.8, you need to:


<ol


  • Review the model specification output to see if your model is correctly specified. You can see the number and names of the variables, latent variables, errors, covariances, paths, etc. You can also see the values and constraints of each parameter. You can use the path diagram or the syntax to check your model specification.



  • Review the data summary output to see if your data are suitable for your model. You can see the number and names of the cases, variables, missing values, etc. You can also see the descriptive statistics and correlation matrix of your variables. You can use the data summary output to check for outliers, missing values, multicollinearity, normality, etc.



  • Review the model fit summary output to see if your model fits your data well. You can see the overall chi-square test of model fit, which compares your model with the saturated model and the independence model. You can also see the degrees of freedom and the p-value of the chi-square test. You can use the chi-square test to check if your model is significantly different from the saturated model or the independence model.



  • Review the fit indices output to see if your model fits your data well. You can see various fit indices that measure different aspects of model fit, such as absolute fit, incremental fit, parsimonious fit, etc. You can also see the recommended values or ranges for each fit index. You can use the fit indices to check if your model meets the criteria for good fit.



  • Review the parameter estimates output to see if your parameter estimates are significant and meaningful. You can see the parameter estimates, standard errors, t-values, confidence intervals, etc. for each parameter in your model. You can also see the standardized parameter estimates, which are easier to compare and interpret. You can use the parameter estimates output to check if your parameters are significantly different from zero and have the expected signs and magnitudes.



  • Review the residuals output to see if your residuals are small and random. You can see the residuals, standardized residuals, modification indices, expected parameter change, etc. for each parameter in your model. You can also see the graphs of the residuals and modification indices. You can use the residuals output to check if your model adequately reproduces the observed data and if there are any large or systematic discrepancies between your model and data.



  • Review the modification indices output to see if your model can be improved by modifying some parameters. You can see the modification indices, which indicate how much the chi-square value would decrease if a fixed parameter is freed or a free parameter is fixed. You can also see the expected parameter change, which indicates how much a parameter would change if it is modified. You can use the modification indices output to check if there are any plausible modifications that would improve your model fit and make theoretical sense.



You can also use the graphs output to visualize your model and data. You can see the path diagram of your model, which shows the variables, latent variables, errors, covariances, paths, etc. with their labels and values. You can also see the factor loading plot of your latent variables, which shows how well they measure their indicators. You can also see the residual plot and modification index plot of your parameters, which show how well they fit your data and how much they can be improved.
