What are H0 and H1 models in JASP ?

Hi,

I have a question regarding regression analysis in JASP.

My question is related to this topic (my apologies to refer you to this, but all is described over there):

What do Intercepts in H0 and H1 models mean ? How is it calculated ?

kind regards and thank you for your help.

H0 should match the sample mean of the dependent variable, it's simply a regression with only an intercept as predictor.

H1 is your model with your selected predictors, in that case the intercept is interpreted as the predicted value on the dependent variable when all your predictors are equal to 0
