Dear Helmut,

❝ However, I guess that simulations in VBA will be extremely slooow.

Perhaps. Maybe Dave can tell us more later. Well, it can be slow, but should not be that slooow.

❝ ...

Sample size: 18

❝ Runtime (seconds):

❝ user system elapsed

❝ 0.14 0.01 0.15

I run the codes three times under R v4.0.3 and got:

Sample size: 18
Runtime (seconds):
   user  system elapsed
   0.11    0.00    0.13

Sample size: 18
Runtime (seconds):
   user  system elapsed
   0.09    0.01    0.10

Sample size: 18
Runtime (seconds):
   user  system elapsed
   0.11    0.00    0.11

a little bit faster. :-D I guess that you have not upgraded to R 4.0.3 yet. R v4.0.3 is simply faster (still my gut feeling :-D). I remember that your Xeon computer runs faster than my Windows, even than my Linux notebook last time. Is it the same computer?

❝ For paranoiacs: Ever heard of macro viruses?

like Melissa? Yes, it's quite possible and should be very careful. But you know we cannot blame VBA. Bad guy is everywhere.

❝ I know of one company not allowing FARTSSIE…...

True. However, some time there is no need to talk to IT department to install R or anything else. Quite ironically.

❝ BTW, in v2.5 of last Tuesday Dave removed all reference-scaled methods and gives the code of PowerTOST in a box. ;-)

Thanks for the information.

All the best,
