LIMDEP and NLOGIT: The Best Choice for Econometric Model Building and Analysis
Unsurpassed Model Capabilities Innovations in Econometrics Programming Tools Maximize Flexibility
LIMDEP and NLOGIT are integrated programs that are unsurpassed in the breadth and variety of their estimation tools. There are over 100 built-in programs for analysis of variance, statistical analysis, and all forms of the linear regression, stochastic frontier, discrete choice and limited dependent variable models, including models for binary, censored, truncated, survival, count, discrete and continuous variables and a variety of sample selection models. There are over 20 different types of models for count data. No other program offers a wider range of single and multiple equation linear and nonlinear models.
LIMDEP and NLOGIT offer state-of-the-art modeling tools for panel data, survival modeling andefficiencyanalysis that are not found in any other program. Numerous innovations have originatedin LIMDEP and NLOGIT. ‘What’s new’ in other programs have been in LIMDEP for years. No other software has combined the fixed effects, random parameters, hierarchical models, mixed models and finite mixture models in such a wide variety of modeling frameworks.
LIMDEP and NLOGIT contain an extensive set of fully integrated analysis tools. All of these interact to produce a studio, or 'laboratory' format for econometric analysis. A set of programming instructions including matrix and data manipulation commands, random number generators and a nonlinear solver allow you to specify and estimate your own model and creatively manipulate all your model estimation results for hypothesis, interval estimation, prediction and simulation.
The Power of NLOGIT
NLOGIT provides the widest and deepest array of tools available anywhere for analysis of discrete choice, including (heterogeneous) nested logit, generalized nested logit, heteroscedastic extreme value, multinomial (and multiperiod-multinomial) probit, mixed logit and panel (repeated measures) estimators for mixed logit, random utility, multinomial probit, and latent class models. NLOGIT is the only program available that supports mixing stated and revealed choice data sets. NLOGIT 4.0 introduces a unique simulation package that allows you to analyze alternative scenarios in the context of any estimated discrete choice model with any data set, whether used in estimation or as hold out data for examining model cross validity. NLOGIT 4.0 also includes all of the features of LIMDEP 9.0.
Post Estimation Tools
After a model is estimated, you can manipulate the results, compute predictions and marginal effects, or other functions of estimated parameters and model predictions.
Accuracy
LIMDEP and NLOGIT use extremely accurate computational methods throughout. As reported in recent publications, they score high marks on all of the National Institute of Standards and Technology benchmark tests for accuracy in ANOVA, linear and nonlinear regression and descriptive statistics.
Easy to Use Interface
Menu-driven command builders allow you to build your models from menus and dialogs while you learn the command language.
Documentation
The manual sets contain full reference guides for the program, background econometrics, and sample applications. The LIMDEP manuals are structured like courses in econometrics, and contain extensive background discussion of econometric models.
