Hi every one.
I have question about statistical analysis in CAT12. I use 2sample T-TEST for statistically analysis of two groups.In building statistical model I used global scaling with TIV. Setting is changed like below:
( Global Calculation → User → Global Values <-X → Define the TIV values here
- Global Normalisation → Overall grand mean scaling → Yes → Grand mean scaled
-value → Define here the mean TIV of your sample (or as approximation a value of
1500 which might fit for the majority of data from adults) - Normalisation → Proportional)
My question is that after changing this setting, which value should I specify for absolute threshold?(in default value:100)
