BIG THINGS HAPPENING

  • After two weeks of not merging in any PRs, I switched it up and merged in Bai’s first so now we just have one outstanding PR left, which we have made a lot of progress on but still need some more progress to get it into dev. Mainly, matching the TMB estimates of uncertainty with the estimates tibble.
  • This week is going to be documentation week. Please see the FIMS calendar for co-working sessions to help out with converting some Google Docs to markdown files.
  • There are lots of issues marked under the CIE Review Milestone. Please feel free to sign up for any that you can accomplish by September 30, 2025.

ANNOUNCEMENTS

  • 50 days until the CIE Review

Thanks to Bai’s recent PR that revamped the lists of lists for running a model into a tibble the amount of code needed to run a default model is even less. Check out the revamped fims-demo-minimal below!

data_4_model <- FIMSFrame(data1)
# Create parameters
parameters <- data_4_model |>
  create_default_configurations() |>
  create_default_parameters(data = data_4_model)
# Run the  model with optimization
fit <- parameters |>
  initialize_fims(data = data_4_model) |>
  fit_fims(optimize = TRUE)
