What's new?

• Palamedes version 1.1.0 is here
  • Version 1.1.0 introduces custom reparametrization of the parameters of PFs in multi-condition fitting situations. See our overview page, PAL_PFLR_CustomDefine_Demo in the PalamedesDemos folder, or type 'help PAL_PFML_CustomDefine' for more information. This was quite a substantive overhaul of many functions (including PAL_PFML_FitMultiple, PAL_PFML_BootstrapParametricMultiple, PAL_PFML_BootstrapNonParametricMultiple, PAL_PFML_GoodnessOfFitMultiple, PAL_PFLR_ModelComparison, as well as many 'behind-the-scenes' functions). Though we spent quite a bit of time testing, bugs might remain and we would appreciate any bug reports. Of course, all previous functionality has been retained (whatever worked with previous versions of Palamedes, will still work).
  • PAL_PFML_FitMultiple can now return the number of free parameters in the model fitted.
  • Added a function PAL_PFML_LLsaturated which returns the Log Likelihood of the saturated model as well as the number of parameter estimates in the saturated model.
  • Some additional minor changes were made (see history.m for the details).
  • Added a few Q and As on our frequently asked questions page.
• We are already working on Palamedes version 1.2.0 which will introduce more Signal Detection routines.

• Palamedes version 1.1.0 coming soon.
  • New feature: custom reparametrization of PF parameters across mutiple conditions. For example:
  • Need to fix the threshold values values in conditions 1, 3, and 6 to equal 1, 2, and pi respectively but have thresholds in conditions 2, 4, 5, and 7 adhere to 'threshold(condition) = a x sin(b x condition^2) where 'a' and 'b' are free parameters? We understand.
  • Wish to compare the model above to an identical one except that parameter 'a' is fixed to equal sqrt(3)? Absolutely.
  • Wish to apply another set of unlikely constraints on slopes, guess rates, and/or lapse rates? No problem.

• Posted version 1.0.1. Very minor changes only:
  • Added a demo script: PAL_SDT_DPtoPCacrossM_demo
  • Other Demo scripts no longer hijack figures that happen to be open
  • Some SDT routines now go easier on RAM
  • Added warning message in PAL_PFML_BootstrapNonParametricMultiple
  • Modified warning message in PAL_PFML_BootstrapNonParametric
  • Added file History.m which records changes across versions
• Download page contains links to two zip archives
  
  • Full Palamedes version 1.0.1
  • Upgraded files only (replace existing files with downloaded files)
