The ACECLUS Procedure

Computational Resources

Subsections:

Let

\begin{eqnarray*} n & = & \mbox{number of observations} \\[0.05in] v & = & \mbox{number of variables} \\[0.05in] i & = & \mbox{number of iterations} \\ \end{eqnarray*}

Memory

The memory in bytes required by PROC ACECLUS is approximately

\[ 8 ( 2n(v+1) + 21v + 5v^2 ) \]

bytes. If you request the PP or QQ option, an additional $4n(n-1)$ bytes are needed.

Time

The time required by PROC ACECLUS is roughly proportional to

\[ 2nv^2 + 10v^3 + i \left(\frac{n^2v}{2} + nv^2 + 5v^3 \right) \]
