How to use this repo

To start using icc/lif/tcc/tif functions, please click this link to get started:

Demo playground in Hedgehog Lab

Here are some examples of using icc/iif/tcc/tif functions (no installation or configuration required):

Item Characteristic Curve (ICC) icc(b,a,c)

*import EDUC412:icc,iif, tcc, tif

b = [-1.0, -0.5, 0, 0.5, 1.0]
a = [2.0, 1.5, 1.5, 1.5, 2.0]
c = [0,0,0,0,0]

icc(b,a,c)

Item Information Function (IIF) iif(b,a,c)

*import EDUC412:icc,iif, tcc, tif

b = [-1.0, -0.5, 0, 0.5, 1.0]
a = [2.0, 1.5, 1.5, 1.5, 2.0]
c = [0,0,0,0,0]

iif(b,a,c)

Test Characteristic Curve (TCC) tcc(b,a,c)

*import EDUC412:icc,iif, tcc, tif

b = [-1.0, -0.5, 0, 0.5, 1.0]
a = [2.0, 1.5, 1.5, 1.5, 2.0]
c = [0,0,0,0,0]

tcc(b,a,c)

Test Information Function (TIF) tif(b,a,c)

*import EDUC412:icc,iif, tcc, tif

b = [-1.0, -0.5, 0, 0.5, 1.0]
a = [2.0, 1.5, 1.5, 1.5, 2.0]
c = [0,0,0,0,0]

tif(b,a,c)

You can copy and paste the above codes or uncomment any of the functions to use them in the Hedgehog Lab playground.
