5 Arguments

1: $\mathbf{order}$ – Nag_OrderType Input

On entry: the order argument specifies the two-dimensional storage scheme being used, i.e., row-major ordering or column-major ordering. C language defined storage is specified by $\mathbf{order}=\mathrm{Nag\_RowMajor}$. See Section 3.1.3 in the Introduction to the NAG Library CL Interface for a more detailed explanation of the use of this argument.

Constraint: $\mathbf{order}=\mathrm{Nag\_RowMajor}$ or $\mathrm{Nag\_ColMajor}$.

2: $\mathbf{p}$ – Integer Input

On entry: $p$, the number of dichotomous variables.

Constraint: $\mathbf{p}\ge 3$.

3: $\mathbf{n}$ – Integer Input

On entry: $n$, the number of individuals in the sample.

Constraint: $\mathbf{n}\ge 7$.

4: $\mathbf{ns}$ – Integer * Output

On exit: the number of different score patterns, $s$.

5: $\mathbf{x}\left[\mathit{dim}\right]$ – Nag_Boolean Input/Output

Note: the dimension, dim, of the array x must be at least

• $\max \left(1,\mathbf{pdx}\times \mathbf{p}\right)$ when $\mathbf{order}=\mathrm{Nag\_ColMajor}$;
• $\max \left(1,\mathbf{n}\times \mathbf{pdx}\right)$ when $\mathbf{order}=\mathrm{Nag\_RowMajor}$.

where $\mathbf{X}\left(i,j\right)$ appears in this document, it refers to the array element

• $\mathbf{x}\left[\left(j-1\right)\times \mathbf{pdx}+i-1\right]$ when $\mathbf{order}=\mathrm{Nag\_ColMajor}$;
• $\mathbf{x}\left[\left(i-1\right)\times \mathbf{pdx}+j-1\right]$ when $\mathbf{order}=\mathrm{Nag\_RowMajor}$.

On entry: $\mathbf{X}\left(\mathit{i},\mathit{j}\right)$ must be set equal to Nag_TRUE if $x_{\mathit{i}\mathit{j}}=1$, and Nag_FALSE if $x_{\mathit{i}\mathit{j}}=0$, for $\mathit{i}=1,2,\dots ,n$ and $\mathit{j}=1,2,\dots ,p$.

On exit: the first $s$ rows of x contain the $s$ different score patterns.

6: $\mathbf{pdx}$ – Integer Input

On entry: the stride separating row or column elements (depending on the value of order) in the array x.

Constraints:

• if $\mathbf{order}=\mathrm{Nag\_ColMajor}$, $\mathbf{pdx}\ge \mathbf{n}$;
• if $\mathbf{order}=\mathrm{Nag\_RowMajor}$, $\mathbf{pdx}\ge \mathbf{p}$.

7: $\mathbf{irl}\left[\mathbf{n}\right]$ – Integer Output

On exit: the frequency with which the $\mathit{l}$th row of x occurs, for $\mathit{l}=1,2,\dots ,s$.

8: $\mathbf{fail}$ – NagError * Input/Output

The NAG error argument (see Section 7 in the Introduction to the NAG Library CL Interface).
