"Latent Class segmentation was the clear winner in our extensive testing of clustering approaches. We don't use traditional clustering techniques anymore and use Latent GOLD to execute all of our segmentation studies"

Overview


Latent GOLD 5.0 is a powerful latent class and finite mixture program. Latent GOLD contains separate modules for estimating three different model structures:

Advanced Option

Latent GOLD 5.0 Basic includes the standard features listed above. The Advanced option includes additional advanced features for continuous latent variables (CFactors), multilevel modeling, and survey options for complex sample data. The Advanced option also includes the Markov GUI module. Learn More


Major New Features in Latent GOLD 5.0

  • Much faster estimation time
  • Improved profiling of classes (see Step3 module)
  • Obtaining equation for scoring new cases (see Step3 module)
  • New GUI for Latent (Hidden) Markov / Latent Transition Modeling
  • New log-linear scale model
  • and more!

Faster Estimation Time

Latent GOLD 5.0 supports multiple processors, making estimation faster than ever! 

Latent GOLD Basic

  • Step3 Module. (See Tutorials) After developing a segmentation model (Step 1), and classifying cases (Step 2), you can now use the latent class segments in followup analyses with the new Step3 module.
    • Get exact equation for scoring new cases
    • Properly adjust for misclassification error
    • Predict classes from exogenous variables
    • Predict exogenous variables from classes
  • Select Cases. The 'Selection Variable' option makes it possible to select a specific subset of cases/records from the data file for analysis.
  • New statistics:
    • SABIC(LL,N), SABIC(L2,N), and total BVR
    • Classification table for proportional assignment
  • Bootstrap p values:
    • Not only of L2, but also for X2, CR2, DI, total BVR, and BVRs
    • In 2LLdif bootstrap, also L2 for H1 model
    • Critical values are reported in addition to p values

Advanced Option

  • Latent (Hidden) Markov GUI. (See Tutorials) How do clusters change over time? Do persons change from one latent class to another over time? Do some persons change (movers) and others not change classes (stayers)? You can now use the new latent Markov GUI to analyze your longitudinal data to address these and many other important research questions. This Markov module is light years ahead of other programs!
    • Unique implementation, not available elsewhere
    • Fastest of all latent Markov programs
    • Quickly analyze even hundreds of time points (other programs can only handle a few time points)!
    • Unique interactive graphics
    • Mixture latent Markov containing multiple indicators
    • Mover-stayer structures
  • New statistics. Based on higher-level sample size for multilevel LC models: BIC(LL,K), CAIC(LL,K), and SABIC(LL,K)

LG-Syntax Module

  • Additional Scale Types. Mixture regression models for dependent variables with other distributions (gamma, beta, von Mises).
  • Scaling Models. New log-linear scale model for categorical dependent variables.


And much more!


Features

  • Full windows implementation - point and click
  • Interactive graphics provide new insights into data and powerful model diagnostic capabilities
  • Flexible model structures can handle variables of different metrics
  • Automatic generation of sets of random starting values
  • Fast, efficient maximum likelihood and posterior mode estimation based on EM and Newton Raphson algorithms
  • Use of Bayes constants to eliminate boundary solutions
  • Bivariate residual diagnostic for local dependencies

Capabilities


Known Class Indicator

This feature allows more control over the segment definitions by pre-assigning selected cases (not) to be in a particular class or classes.

Conditional Bootstrap p-value

Model difference bootstrap can be used to formally assess the significance in improvement associated with adding additional classes, additional DFactors and/or an additional DFactor levels to the model, or to relax any other model restriction.

Overdispersed (Count and Binomial Count in Regression)

Overdispersion is a common phenomenon in count data. It means that, as a result of unobserved heterogeneity, the variance of the count variable is larger than estimated by the Poisson (binomial) model. The overdispersed option makes it possible to account for unobserved heterogeneity by assuming that the rates (success probabilities) follow a gamma (beta) distribution. This yields a negative-binomial model for overdispersed Poisson counts and a negative-binomial model for overdispersed binomial counts. Note that this option is conceptually similar to including a normally distributed random intercept in a regression model for a count variable.

The overdispersion option is useful if one wishes to analyze count data using mixture or zero-inflated variants of (truncated) negative-binomial or beta-binomial models (Agresti, 2000; Long, 1997; Simonoff, 2003). The negative-binomial model is a Poisson model with an extra error term coming from a gamma distribution. The beta-binomial model is a variant of the binomial count model that assumes that the success probabilities come from a beta distribution. These models are common in fields such as criminology, political sciences, medicine, biology, and marketing.
