Real Time data #18

Closed EverAPC closed 4 years ago

EverAPC commented 4 years ago

Hi, Can the code be applied to real time data in the place of simulated ones.

douglasrizzo commented 4 years ago

It can. I have some examples where you can use initializers, selectors, estimators and stoppers inside your own code or script, without a simulator.

Just to be clear, your program will be responsible for providing item parameters and students responses, and catsim will provide proficiency estimations, which items to apply next and or not a test must be stopped.

Hi, Thank you for the immediate clarification. I have few more concerns: 1) Can't this be used for polytomous outcomes?2) Can this be used to give a score for a particular item?3) Should this be used only for CAT purposes? Thank you  Warm Regards,Princy On Wednesday, November 27, 2019, 02:55:19 AM GMT+5:30, Douglas De Rizzo Meneghetti notifications@github.com wrote:

  1. No, only dichotomous answers;
  2. If, by score, you mean estimating item parameters, then no;
  3. I don't know what do you mean by that. I am going with the hunch you're looking for an IRT package made in Python and not explicitly a package focused on adaptive testing. catsim has a module with functions for the 1 2 3 and 4PL models, but I don't believe it is a full replacement for specialized packages available in other languages, such as the mirt package in the R language.
