CCRR: Conditional Correct Response Rate
Description
The conditional correct response rate (CCRR) represents the ratio of the students
who passed Item C (consequent item) to those who passed Item A (antecedent item).
This function is applicable only to binary response data.
Usage
CCRR(U, na = NULL, Z = NULL, w = NULL, ...)
Value
A matrix of conditional correct response rates with exametrika class.
Each element (i,j) represents the probability of correctly answering item j
given that item i was answered correctly.
Arguments
- U
U is a data matrix of the type matrix or data.frame.
- na
na argument specifies the numbers or characters to be treated as missing values.
- Z
Z is a missing indicator matrix of the type matrix or data.frame
- w
w is item weight vector
- ...
Internal parameters for maintaining compatibility with the binary data
processing system. Not intended for direct use.
