{p 4 4 2}{it: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.
|

|
|
|
||
|
|
{p 4 4 2}{cmd:partition} permit to define the number of items in each dimension. The user must precise in the {it:numlist} the number of items in each dimension.

{title:Description}

|
|
|

|
|
{p 4 4 2}{cmd: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).

{title:Remarks}

|
{p 4 4 2}For detailed information on the DETECT, Iss and R indexes, see Zhang and Stout (1999).
|
||
|
|
|
||
|
|
{p 4 4 2}{cmd:detect} don't permit the use of polytomous items.
