New features in LISREL 8.7 for Windows

  • Generalized Linear Models (GLIMs) for complex survey data

    The new SurveyGLIM module in LISREL 8.7 allows users to select from the multinomial, Bernoulli, binomial, Poisson, negative binomial, gamma, Gauss, and inverse Gaussian sampling distributions. Various link functions, such as the log, cumulative logit, cumulative probit, complementary log-log, and logit are available.

    SurveyGLIM allows for the analysis of data from a simple random sample or from a complex sample design. In the latter case it is assumed that the population from which the sample is obtained can be stratified into strata. Within each stratum, clusters (primary sample units or PSUs) are drawn and within each stratum-cluster combination, the ultimate sampling units (USUs) are drawn with specified design weights. There is also an option to correct for finite populations, provided that the sampling rates or population sizes are available.

  • Implementation of design weights in the LISREL Multilevel modeling module

    There has been a growing interest in recent years in fitting models to data collected from surveys using complex sample designs. LISREL 8.7 features an option for users to include sample design weights for the analysis of hierarchical linear models. This makes it possible to specify weights on levels 1, 2 or 3 of the hierarchy. Correct parameter estimates and robust standard errors are produced under complex sampling designs.

  • Implementation of sampling weights for SEM models when data is missing at random

    In previous versions of LISREL, users were able to compute the appropriate covariance and estimated asymptotic covariance matrices for continuous variables via PRELIS given a normalized weight variable. These matrices are only produced in the case of complete data, or using list-wise deletion in situations where missing data values are present.

    In version 8.7, it is possible to use design weights to fit SEM models to continuous data with missing values. The easiest way to do this is to define the weight variable once a PSF file is displayed. A full information maximum likelihood (FIML) method is used to obtain the correct parameter estimates and robust standard errors given the sampling weights.

  • Multivariate Censored Regression

    Univariate regression for a censored response variable is available since LISREL 8.54. In LISREL 8.7, this method is extended to allow for multivariate censored regression. In addition, the appropriate sample covariance matrix for a set of censored variables may be computed and used to fit structural equation models to censored data.

  • Goodness-of-fit statistics

    Since the release of LISREL 8.52 for Windows, the computation of the chi-square test statistic value for the independence model is based on the normal-theory weighted least squares (NT-WLS) chi-square test statistic value rather than on the minimum fit function chi-square test statistic value. This change implied that the goodness-of-fit statistics, which is based on the chi-square test statistic value for the independence model such as the CFI, NFI, NNFI, IFI, etc., were different and led to numerous inquiries by our LISREL users. As a result, LISREL 8.7 produces an additional file with the file extension 揊TB?that contains a listing of these goodness-of-fit statistics based on all four chi-square test statistic values that LISREL 8.7 reports.

  • Changes to the windows/menus/dialogs

    There are three new options in the Compute dialog box starting with version 8.7 of LISREL. These are: (i) TIME (ii) AUTOLAG/ORDER, (iii) CHISQ(DF)

    The first option enables users to create a new variable called TIME, that assumes integer values 1, 2, 3, ? ncases. Functions of TIME, for example TIME**2 can also be computed. The second option allows the user to create new variables that assumes the same values than an existing variable, but with a user-specified lag. These new variables are useful in identifying time series processes and for the calculation of lagged correlation matrices. Lastly, one can generate random deviates from a chi-square distribution with a specified number of degrees of freedom.

    Additions/changes to the dialog boxes of the multilevel module include: (i) No-Intercept option (ii) Select weights list box (iii) Print asymptotic covariances checkbox (iv) Print values of within and between covariance matrices checkbox. Note that the specification of a level-1 ID variable is no longer required.

LISREL

LISREL is a software product designed to estimate and test Structural Equation Models (SEMs). Structural Equation Models are statistical models of linear relationships among latent (unobserved) and manifest (observed) variables. You can also use this software to carry out both exploratory and confirmatory factor analysis, as well as path analysis.

Request: Structural Equation Modeling: Present and Future A Festschrift in honor of Karl Jöreskog

Robert Cudeck, Stephen du Toit & Dag Sörbom (Editors)

The text honors Dr. Karl Jöreskog's outstanding academic career through contributions of current researchers in Structural Equation Modeling.

The book contains the following sections:

  • Part A: History and Perspectives: This section will be indispensable to educators and students alike who want to explore the roots of factor analysis, including some more personal accounts by two of Dr. Jöreskog's former students.
  • Part B: Robustness, Reliability, and Fit Assessment: Six chapters explore the evolution and current execution of the methodology in greater depth.
  • Part C: Repeated Measurements, Experimental Design: Investigations and discussion of longitudinal data analysis, including some new approaches to model design.

  • Part D: Ordinal Data and Interaction Models: Some modern extensions of structural modeling theory are explored and expanded in this section.

For depth and breadth, Structural Equation Modeling: Present and Future is definitely a worthy addition to the library of anyone who is involved in the field. Overall, it will provide wonderful insight into the progress that has come from the ongoing work of Dr. Jöreskog and countless others in Factor Analysis and Structural Equation Modeling.
