UCLATALL Supernova Versions Save

New Features

• Added the ability to change the type of sums of squares to calculate when computing the ANOVA tables. Users can choose from 1/I/sequential, 2/II/hierarchical, 3/III/orthogonal.
• Added pedagogical function generate_models() for showing which models are being compared when evaluating terms in a model. This function also supports specification of the type of sums of squares to use.

Minor Changes

• Created and added a logo to the package.
• Added a NEWS.md file to track changes to the package.
• Updated the README to be generated from an Rmd file and to include information and examples regarding how to calculate different SS types and how to use generate_models()
• Added a data frame identical to Servers named Tables. This is a more appropriate name for the dataset because each row describes what happened at a table in the restaurant.
  • Updated variable names and documentation to "table" as well.
  • Added deprecation notice to Servers documentation as the table will be removed in the future.

supernova() now supports multiple regression using Type III sums of squares. See the README for more information, examples, and a description of how the calculation of the ANOVA tables follows the model comparison approach used in Judd, McClelland, & Ryan (2017).

This version of supernova is the original distributed on CRAN. Calculation of supernova() tables with multiple predictor variables will not produce output similar to the reference text, Judd, McClelland, and Ryan. However, single predictor regression matches.
