(See the part 1 post here.) Viewing and changing your working directory One step will be changing your working directory to the place where you actually want to be working. See your current working directory with “pwd()“. Note: if you get a message saying “pwd (generic function with 1 method)”, you entered “pwd” and not …

I recently had to make a figure that showed relationship between variables. I tried a few different software packages and ultimately decided that Graphviz is the easiest. Thanks to dreampuf for their Graphviz online program! I used this web-based implementation and didn’t have to install Graphviz on my computer. So for this, we’ll be using …

I’m a Linux novice and installed Stata 18 on my new Ubuntu 24.10 dual boot laptop. But! Stata doesn’t show up as an installed program in my launcher. I found the installed files, including the executable for the GUI-based version of Stata 18 (“xstata-se”) in the /usr/local/stata18/ folder. I wanted to make a desktop shortcut …

There are all sorts of models out there for performing regressions. This page focuses on 3 that are used for binary outcomes: Getting set up Before you get going, you want to explicitly define your outcome of interest (aka dependent variable), primary exposure (aka independent variable) and covariates that you are adjusting for in your …
I recently made a figure that estimates a hazard ratio and renders it right on top of a Kaplan Meier curve in Stata. Here’s some example code to make this. Good luck!
I recently had to make some boxplots with Stata’s –graph box– command. I find this to be challenging to use since it varies from syntax from the –twoway– command set that I use all the time. I was using the –over– subcommand x2 and wanted to change the colors of each box & dots by …

Frames were introduced in Stata 16 and are handy for (a) storing/manipulating multiple datasets simultaneously and (b) building datasets on the fly. I’ve had good luck making a table using frames. This strategy includes (1) making a new frame with as many columns as you need, specifying they are long strings (strL), and printing the …

I recently had a dataset with two groups (0 or 1), and a continuous variable. I wanted to show how the overall deciles of that continuous variable varied by group. Step 1 was to generate an overall decile variable with an –xtile– command. Step 2 was to make a frequency histogram. BUT! I wanted these …

Stata has some handy built-in features to make boxplots. If you are trying to make a typical boxplot in Stata, go read up on the –graph box– command as described on this post. I was asked to abstract a boxplot from an old paper and re-render it in Stata. I used the excellent WebPlotDigitizer to …
I was the analyst for the myPACE trial (published here in JAMA Cardiology), and needed to put together a subgroup analysis figure. I didn’t find any helpful stock code, so I wrote my own. The code uses the Frames feature that was introduced in Stata 16. It will (a) make a new frame with the …
