Dear Helmut,

» However, I guess that simulations in VBA will be extremely sloo_ow.

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

» 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?

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.
