[Bonitta gianluca]

Thank You for soon reply fisrt of all

i have the dataset and r script maby i can send and you can help to 
prototipe the script in r ...for example



for professor Ben :

i had seen long power pack but i think this need repeated measure for the 
use i have not repeated measure ...do You think is possible to suite long 
power pack for my case?



I have also try simulative way for post hoc power calculation.... but this 
yeld pap power analysis paradox... when p-value is "big" power is low , 
when p-value is "small" ower is hight  so i prefer to determinate a priori 
power ....

thank you so much
