Changes: * Change default behavior for factor simulations, order of levels are maintained now instead of alphabetical order which is the default in R.

  • Small maintenance fix for incoming 0.8 dplyr.
  • Release for new tidy simulation framework
  • New vignettes showing this functionality
  • Add piecewise linear simulation.
  • Add cross classified model simulation
  • Add option to specify any model to fit for power analysis
    • This brought about a change to use broom::tidy.
  • Generalize fact_vars code
    • This now is similar to cov_param
  • Shiny Application works again!
    • Can now simulate and run power.
    • Able to download simulation and power tables (I think).
  • Fixed basic functionality of Shiny application
    • This includes simulation and power
      • Needs more testing at this stage.
  • Addition of count outcome from sim_glm.
    • This added an additional argument that must be specified:
      • outcome_type = ‘logistic’ = 0/1 dichotomous simulation
      • outcome_type = ‘poisson’ = count outcomes.
  • Bug fix for sim_glm when using fact_vars generation options.
  • Heterogeneity of variance simulation
  • Flexible time specification for longitudinal models
  • Change ‘lvl’ to ‘level’ throughout package
  • Flexible specification of unbalanced simulation
  • Misspecification of model for power analysis
  • Expand power output.
  • Update to add ability to simulate covariates from any R distribution function
    • Old code will no longer work with this new version.
    • Added new opts argument to cov_param for optional distribution arguments.
  • Adjusted vignettes to follow new code
  • Adjusted unit tests.
  • Added documentation for changes, including in vignettes.
  • Added a NEWS.md file to track changes to the package.
