We are releasing a major update for stats4ROI! The changes are mostly behind the scenes, but this should make maintaining the app easier going forward. It is the first release with the new architecture, so let us know if something is missing.
I have also automated the package installation with a script, so that makes installation easier if you are choosing the R or RStudio installation path.

- No new packages needed
- Added Features
- Entirely new architecture that hopefully has no visual impact on the user. This moves away from the monolithic 33,000 line app and distributes the code out to modules to do the work. I have verified the outputs matches the original app.
- Added sample size calculation for estimation. The interface asks you how wide you want the confidence interval to be and calculates a sample size to achieve that.
- Added the Weibull distribution.

Bug Fixes
-
Fixed bug that would show a slight error for the one sample variance test standard deviation confidence intervals.
- There were numerous small bug fixes found during the refactoring.
-
- Known issues:
- Due to the new architecture there is 12 seconds or so once you load the app where it creates all the UI in all the tabs and screens. This is inherent in using a rather large number of UIs across multiple modules. There may be a way to work around this, but it will be a major undertaking. After the delay, all UIs everywhere should be nearly instantaneous in loading, so this should be a minimal inconvienence.
- datamods no longer will load .dat files with only one column - this is a limitation in the packages it uses. A fix is in the works. A workaround is to save that as a .txt file or just cut and paste the data.
- If you run the app from RStudio and you have clicked on a line number to add a breakpoint, it will take a long time to load the app - this is due to RStudio functions that take 10+ seconds to load. Once they are loaded, it does not affect the app. Consider loading via RGui if this is an annoyance since it loads immediately there. This does not happen if you avoid adding a breakpoint that way.
- Lin-Mudholkar test fails due to breaking the function when the correlation is 1 (lolcat issue)
- No button on MVP(E) or Mann-Whitney-U test to stop early - may be added in the future
- The density plot x-axis for the exponential will start at zero even if the minimum is above that. This seems to be built into ggh4x.
