naginterfaces.library.contab.binary_service(x)[source]

binary_service is a service function which may be used prior to calling binary() to calculate the frequency distribution of a set of dichotomous score patterns.

The number of different score patterns, .

xbool, ndarray, shape

The first rows of contain the different score patterns.

irlint, ndarray, shape

The frequency with which the th row of occurs, for .

Notes

When each of individuals responds to each of dichotomous variables the data assumes the form of the matrix defined below

where the take the value of or and , for , denotes the score pattern of the th individual. binary_service calculates the number of different score patterns, , and the frequency with which each occurs. This information can then be passed to binary().
