Either we use a priori the Assumption 4 or investigate 𝐼(𝐽𝑑;𝐽0).IJd;J0. If 𝐼(𝐽𝑑;𝐽0)IJd;J0 is not converging to zero, we can not perform further causal discovery without collecting more information about our subject. If 𝐼(𝐽𝑑;𝐽0)IJd;J0 tends to zero...
the robustness of our findings is constrained by the small sample size. An “a priori” sample size calculation indicated a total sample size of 102 subjects (34 per group) for conducting a repeated measures ANOVA with three groups, four measurements, an effect size of 0.25, an alpha-error ...

'propositions' to physical and perceptual (especially visual) reality, and that the way in which Wittgenstein broaches this problem differs radically, in spite of apparent similarities, from that which characterizes theories of the visual a priori in terms of stipulations (notably Carnap's theory ...
The same investigator performed and scored all the measurements for each subject. 2.2. Statistical Analysis Outcome variables were tested and visually inspected a priori for normality with the Shapiro-Wilk test and Q-Q plots. The normality assessment revealed that BBS-14 and COParea did not meet ...
