In mrkaliv/logreg: Builds a logistic regression one variable at a time

knitr::opts_chunk$set(echo = TRUE)

Accuracy

• Are the results accurate?

  I am not sure. Once I opened the app, I expected that checking the variables would include them in the model, but it includes all of the unchecked variables. I think a little bit of explanation on the app page would be helpful.

• Is it clear how the results were computed?

  As far as the calculations the drive the shiny app, they are not. The README file does discuss the GLM method that I assume is used in the app, which does appear to be correct. It was unclear what data was being used to do the calculations without the GLM line instruction however.

Compilation

• Did the analytic work? (i.e. install correctly, startup correctly)

  The only issues I encountered were with installing/updating the Rcpp package, which is likely an error on my machine.

• Were errors encountered when executing code according to the documentation?

  The shiny app loaded correctly and had consistent functionality for all of the options. No issues encountered.

Ease of use

• Is it clear how to use the analytic? (i.e. is the documentation clear)

  The README was very clear on how to load the package and the GUI; however, it was unclear what exactly the stepwise regression was working on. I did eventually find the dataset, but did not realize at first that it was a fixed dataset that I could not change.

• Are the visualizations/plots interpretable?

  The table very clearly displays the regression variables (though it could have better column names). I actually really like the search feature, but I'm not sure it's necessary on a limited dataset.

Final Grade - Please provide a final grade I would recommend a grade of Satisfactory:

• The documentation was fairly limited

• The data set was fixed, but not clear that that was the case (if it was designed for custom data, it did not indicate as such clearly)

• The app appeared to work against what was intuitive (check marks excluded the variable as opposed to include).
