Description
The original dataset consists of responses from 1,000 subjects to five
dichotomous items from section 6 of the LSAT exam. The version here
is presented as frequencies of unique patterns of responses. The data
is from Bock and Lieberman 1970.
Usage

Format
A data frame with 32 observations on the following 7 variables. The
variable wt7 represents the number with each pattern.
y1a numeric vector
y2a numeric vector
y3a numeric vector
y4a numeric vector
y5a numeric vector
wt6a numeric vector
wt7a numeric vector
