The most advanced version of AroniSmartStat™ ever is available in App Store®. 

What is new AroniSmartStat™

To increase the power and effectiveness of AroniSmartStat, the algorithms for advanced applied statistics and data mining models have been optimized.The following models have been optimized.

 

• Hierarchical Mixed Effects Models:

AroniSmartStat™ supports Hierarchical Mixed Effects Models. The selection of Hierarchical Mixed Effects Models opens up the “Mixed Effects Model Specifications” window, in which the options are set. Depending on the model structure, fixed effects, random and grouping effects need to be set.

If only fixed effects are selected, the model becomes a general linear regression model.

Selecting both random and fixed effects make a regular mixed effects model. In order to setup a hierarchical mixed effects or a Linear mixed effects model for repeated measures, grouping variables (level 1 or 2 micro units, or subjects) need to be selected. Selecting multiple grouping variables implies nested units.

Hierarchical Mixed Effects Models accept interaction models.

Fixed Effects and Random Effects interaction models are set in the bottom of the window. Grouping effects still need to be selected in the grouping browser.

Example: Intercept+X1+ X2+X1*X2+X3|X4 is equivalent to Intercept+X1+X2+X1*X2+X3+X4+X3*X4.

Econometrics Models. 

Econometrics Models controller contains a series of models used in Econometrics. The econometrics models included are:

  • Count Data (Poisson, Negative Binomial),
  • Logistic Regression,
  • Logit,
  • Probit,
  • Tobit,
  • Interval,
  • Weighted Least Squares,
  • Ordinary Least Squares (OLS)

Some Econometrics Models, such as Logistic Regression, and OLS may be run outside Econometrics Models.

Each Econometrics model may have its own options that should be set before running the model.

For example, choosing Count Data Models requires selecting he distribution: Poisson, Negative Binomial, etc. 

Same for Probit where the user needs to choose among the following distributions:

  • Binary,
  • Ordered, and
  • Random Effects,

 Logit where the choices are:

  • Binary,
  • Ordered, and
  • Multinomial.
