Moderation Medmod

[Anne]

Hi!

I was doing a moderation with the medmod module. I used a dichotomous predictor with the values 1/2. The x-axis in the associated plot shows the endpoint -0.5 / 0.5. Is this due to standardization processes?

Thanks for your help!

Hi Anne,
Yes this is indeed because all variables are centered before the analysis is run, see https://github.com/raviselker/medmod/blob/6f81b0fa009a97cf11c808f7ee561097e7c1310a/R/mod.b.R#L198-L201.

Cheers,
