[Use of personal computers for statistical analyses].
We report the range in elapsed time for various statistical analyses and for the same logistic regression analysis in 23 different personal computers (PCs). Without a floating-point coprocessor, the elapsed time increased from ten to 113 minutes in the same PC. Elapsed time ranged from two to 45 minutes from 80486 to 8086 PCs with a floating-point coprocessor. The PC equipment we need strongly depends on the type and frequency of the statistical analyses we are to perform. If a floating-point coprocessor is installed, the 80286/80287 PC family may be fast enough for most users.
