Here we are going to look at several diagnostic plots that are helpful when attempting to answer a causal question. They can be used to visualize the target population, balance, and treatment effect heterogeneity.

Are two wrong models better than one? Missing data style

Would imputing + fitting an outcome model using the wrong variables be better than just fitting the wrong outcome model? Let’s investigate!

When is complete case analysis unbiased?

rstats
simulations
missing data
I have been thinking about scenarios under which it makes sense to use imputation for prediction models and am struggling to come up with a case. Yikes! Even for inference, as long as you do some doubly robust approach, I’m not sure I see the value (other than for precision, but then is no longer a question of bias and thus is a question for a different day!)

On this weeks episode of Casual Inference we talk about a “Causal Quartet” a set of four datasets generated under different mechanisms, all with the same statistical summaries (including visualizations!) but different true causal effects.

Transparency in Public Health

Transparency in public health messaging matters. Hannah Mendoza and I looked at how providing transparent information about why a public health recommendation is being made can increase uptake in a randomized trial published today in Plos One.

The Peril of Power when Prioritizing a Point Estimate

I recently noticed that the Pfizer immunobridging trials, presumably set up to demonstrate that their COVID-19 vaccines elicit the same antibody response in children as was seen in 16-25 year olds, for whom efficacy has previously been demonstrated, have a strange criteria for “success”.

Exploring the impacts of noninferiority trial thresholds

This post explores the impact of setting particular criteria for ‘success’ in clinical trial designs, with a specific example from the recent vaccine immunobridging trials.

Would seeing Spider-Man: No Way Home decrease COVID-19 Cases?

causal inference
In SNL’s cold open last night, President Joe Biden suggested that the COVID-19 surge we are seeing in the US is due to people seeing Spider-Man: No Way Home. If people would just stop seeing this film, he argues, cases will go back down! Interesting hypothesis, let’s take a looksy at the data, shall we?
