Fictitious data set from Doignon and Falmagne (1999, chap. 7).
Response patterns of 1000 respondents to five problems. Each
respondent is assumed to be in one of nine possible states of
the knowledge structure `K`

.

A list consisting of two components:

`K`

a state-by-problem indicator matrix representing the hypothetical knowledge structure. An element is one if the problem is contained in the state, and else zero.

`N.R`

a named numeric vector. The names denote response patterns, the values denote their frequencies.
