I hope you are doing well.
I have one doubt about backend functioning of R command.
Currently I'm working on IRT analysis in python but this function is
implemented in R and in R they have direct rasch model library but no
such library in the Python.
So i wanted to know that is there any way to find the math or formula
behind the specific command of R language.
for eg, summary(PL2.rasch)
after this command you will directly get difficulty and discrimination
values like mentioned below:
value std.err z.vals
Dffclt.V1 3.1135 9.8208 0.3170
Dffclt.V2 -0.5157 0.8941 -0.5768
Dffclt.V3 -1.3585 3.2062 -0.4237
Dffclt.V4 -1.0032 8649.3103 -0.0001
Dffclt.V5 0.0400 1350.8452 0.0000
So is there any way to find out the math behind this summary command ?
