Hi Randall, Thanks for the email.
I was indeed quite happy to see your PDF on the Lock website when I began teaching the course. The last time I looked at your PDF, it it looked like it was mostly code to do replicate their examples in R, which while helpful, isn't quite what I'm looking for. I'd love for them to learn R in that manner, but I think it's slightly beyond their skill set. Ideally here's what I'd like. I would have the StatKey interface for bootstrapping and randomization tests written in Shiny (or a similar toolkit with R as the backend) such that there is a main plot that shows the bootstrap or randomization distributions (with an option to set the seed) and two side plots to show the original sample and the current bootstrap/randomization sample. If possible, I'd like the "current" sample plot to be updated based on the statistic that is hovered over in the main plot (probably this could be done with ggplot2 and an additional package or d3.js). As far as I can tell nothing like this exists for R or Shiny (I'd love to be wrong, though). So, basically a one-to-one port of StatKey to R. It would be great to see this functionality packaged in a Shiny app under a tab called "Inference via Simulation". Another tab might be called "Theory-based Inference" (or some better name), that provided a drop down menu to select a test (binomial, t-test, regression, ANOVA, chi-square), an option to calculate an arbitrary CI, a plot of the data for assumption checking, model output printed, and a plot showing the p-value all within that tab. This could be broken up to make it a little less busy. Finally there might be another tab for just "Exploring the Data" both numerically or graphically (essentially a tab for EDA). Additionally, there might be the option to show/hide the R code. I would like students to be able to upload the data as a CSV to the app. I've got quite a bit of experience making Shiny apps, but don't want to create one if someone has already made something similar to this that I could either fork or just use. Regarding JASP and jamovi, I found their language to be weird and creating confidence intervals cumbersome. E.g., creating a confidence interval for a mean, as far as I could tell, requires running a one sample t-test, making sure H_0 the Test Value(?) is set to 0 otherwise the CI won't make sense, clicking location parameter, and then setting the confidence interval and hoping the students don't select effect size instead, which they do. In JASP, you can't edit data directly but must edit it in Excel. and you can edit directly in Rcmdr. JASP's focus on Bayesian is also confusing for my non-Bayesian course as students select the wrong tests very easily. I do love that they have the ability to export to LaTeX tables by default, very nice. Also, in JASP you can't get dot plots, which I think are very helpful for teaching. Neither software is capable of bootstrapping and randomization tests as far as I know.
