What advantage does PROC FASTCLUS offer for very large datasets compared to PROC HPCLUS?
Select an answer to reveal the explanation.
Short Explanation and Infographic
Here's the deal — c is correct because PROC FASTCLUS is designed for efficiency on large datasets, assigning observations to the nearest cluster and using MAXITER= and drift control to achieve fast convergence, including options for reading data only once. A is wrong; PROC FASTCLUS uses random seed-based initialization.

Full Explanation
C is correct because PROC FASTCLUS is designed for efficiency on large datasets, assigning observations to the nearest cluster and using MAXITER= and drift control to achieve fast convergence, including options for reading data only once. A is wrong; PROC FASTCLUS uses random seed-based initialization. B is wrong; BIC-based selection is not a PROC FASTCLUS feature. D is wrong; PROC FASTCLUS uses Euclidean distance.
