The gfoRmula package is available on CRAN. cran.r-project.org/web/packa… All #Rstats users can now implement the parametric #gformula for #causalinference with time-varying treatments and confounders. For a detailed software guide, see arxiv.org/abs/1908.07072 Have fun, everybody!

Our new(ish) @DrugAlcoholDep paper is up! We compare common longitudinal modelling approaches to tracking the trajectory of substance use across adolescence and young adulthood: doi.org/10.1016/j.drugalcdep…

I'm looking for a key resource on latent growth modelling specifically. Hopefully something covering latent curve models, growth mixture models, and latent class growth analysis - discussing assumptions, etc. Any leads? HELP @gjyacademic

Our review of #MachineLearning in #mentalhealth is finally out - woohoo! Synthesising 300 papers was no easy task; hopefully it's useful for those looking for some ideas in this space.

Interested in working with a 25-year longitudinal study for our 11th wave of participant follow-up? @2000stories are looking for a data collection coordinator (bit.ly/2RGfD2r), and participant tracing/engagement specialist (bit.ly/2RFJdVS). Please share!

Can someone point me towards some machine learning methods/packages for variable/feature selection that can handle missing data (e.g. using multiple imputation)? Found this so far: ncbi.nlm.nih.gov/pubmed/2352… #rstats
Variable selection for multiply-imputed data with application to dioxin exposure study - PubMed

Variable selection for multiply-imputed data with application to dioxin exposure study - PubMed

Multiple imputation (MI) is a commonly used technique for handling missing data in large-scale medical and public health studies. However, variable selection on multiply-imputed data remains an...

You know you’ve spent too long in Stata when: you start misreading food labels and think even your lentils are imputed.

Great read to get you thinking about causal inference in observational studies teapaw.org/_MiguelHernan/status/9…

The C-word: "We need to stop treating #causal as a dirty word that respectable investigators do not say in public or put in print." Not saying "causal" harms science. Saying "observational studies cannot prove causation" misses the point. I explain here ncbi.nlm.nih.gov/pubmed/2956…
