One sided t-tests #115

Closed mike214999 closed 4 years ago

Dear SPMlers

After some time I realized that my significant results were always two-tailed instead of one-tailed (that fits my hypothesis). However, when using ti = t.inference(0.05, two_tailed=False) it seems that it only tests in one direction as the result is not significant anymore. How can I instruct the model to test in the opposite direction ?

Thanks for help! Chris

Have you tried to switch yA and yB params? Because as you have a directional hypothesis, you should always put the data in a specific order.
