TSK: Thresholds, Skewness, and Kurtosis
In Boklauth/AUTTT: A Unified Treatment in Test Theory
TSK R Documentation
Thresholds, Skewness, and Kurtosis
Description
This package contains the TSK function TSK(),
which allows you to calculate thresholds, skewness, and kurtosis
give categorical response probabilities.
Usage
TSK(n, res_prop)
Arguments
n
A sample size as an interger.
res_prob
A vector of categorical response probabilities.
Value
TSK will return threshold values and corresponding response probabilities and cumulative probabilities.
It will also return skewness and kurtosis values. Kurt1 uses the regular formula of kurtosis
but it subtract the value with -3. Kurt2 is the original value.
Kurt3 uses formula found in Sheskin (2000).

# Probability of each response category

res3<-50/120
res4<-50/120
res.prop<-c(res1, res2, res3, res4)
