I’m a big fan of Stata because of its simplicity and excellent documentation. I have a lot of colleagues that use R and I see why they like it, but I’m not a fan of the R syntax. I’ve played with Python and liked the syntax quite a bit but found simply installing Python and …

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 …

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 needed to make a figure for publication and the publisher didn’t like the resolution of the figure that I provided. One option is to increase the number of pixels of the rendered figure (eg increasing the width and height), the other is to create a figure using vectors that can be zoomed in …
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 …

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 …

If you like automating your Stata output, you have probably struggled with how to format P-values so they display in a format that is common in journals, namely: If P>0.05 and not close to 0.05, P has an equals sign and you round at the hundredth place E.g., P=0.2777 becomes P=0.28 If P is close …
