Learn R Programming

⚠️There's a newer version (3.1.7) of this package.Take me there.

abn devel project (PRIVATE)

structure

  • abn/ contains source code
  • Use testthat for tests

Modifications

  • bug correction for simulation and prediction
  • plot function with mb, fitabn output
  • implementation of forumla in: Buildscore/fitabn (modification of rd file)
  • plot function + rd file
  • prediction function + rd file
  • simulation function + rd file

To do:

R Package (release)

  • rd file: plot, simulation, prediction
  • implementation of test for plot/prediction/simulation functions
  • diagnostic plots
  • bootstrapping
  • Implement parallel computing in fitabn(), buildscorecache()

R package (extension):

  • Implement new prior MP (multinomial + data separation)
  • Data separation
  • Random effect (already one layer)
  • Multinomial
  • Negative binomial, ...
  • Time/Memory resources optimization
  • Handling missing data
