Agenda & Minutes

New content in

  • GLMM - Miriam

  • CI for props - split into 5 sections Poisson rate CI’s separate to binomial, PR in, awaiting review/approval.

  • Survival Cox_PH model using survival::strata, issue prior to Version 3.8.0

  • Upgrade of renv to later R version, led to many files changing 100+ files. So make sure you pull down latest repo before you do a PR.

  • upgrade also led to different code needed for SAS code / SAS files. Use 3 back ticks & {SAS} instead of {r} and #|eval: false . see Generalized Linear Mixed Models (GLMM) SAS file as a good example.
