Dear William:
I'm wondering does Probability of a causal impact is all most all the time around 50?
I noticed most of probability appears 50 percents.
I'm trying to figure, what is the difference between tf casual package and R, . in R 90 percent for probability of casual impact. I used the same samples and run for multiple testing. would you help me to understand the main difference and what is causing huge difference in p value output.
