Dear Helmut!

❝ ... In the meantime I finished my balanced cross-over sim’s. n 12–60, CV 6–100%. With my grid I have 306·10⁶ sim’s each. With rounding I got 24 (7.84%) empiric alphas significantly >0.05; without 11 (3.59%).

How do you interpret the un-rounded results?
Empirical evidence of an Alpha inflation of TOST :cool:

?
Hopefully not.

❝ Sometimes R drives me nuts.

Here I have another one:

round(c(1.2500499999999999, 1.250049999999999999), 4)

[1] 1.2500 1.2501

More trouble spots can be found in "The R inferno".
Should be a must-read for all R-users.
