DETECT Index

        detect varlist , partition(numlist) [noscores norestscores]


    varlist is a list of two existing dichotomous variables (items) or more.
    The first items of this list compose the first dimension, the following
    items define the second dimension, as so on.

    partition permit to define the number of items in each dimension. The
    user must precise in the numlist the number of items in each dimension.

{Options}

    noscores permit to remove the table of the correlations between the items
    and the scores

    norestscores permit to remove the table of the correlations between the
    items and the rest-scores


Description

    detect permit to compute the DETECT index (Dimensionality Evaluation to
    Enumerate Contributing Traits), as the Iss (Approximate Simple Structure
    Index) and the R indexes defined by Zhang and Stout (1999).


Remarks 

    For detailed information on the DETECT, Iss and R indexes, see Zhang and
    Stout (1999).

    detect don't permit the use of polytomous items.

Example

        . detect item1 item2 item3 item4 , partition(2 2) nosco norest

        . detect item1 item2 item3 item4 item 5 item6 item7 , partition(3 2 2)
