Sign of the drift rate in the ADDM

[Jiashun97]

Hi Max,

Thanks for your recent update of the pyddm package. It looks great! I am now implementing the ADDM by customizing the drift rate. I was wondering if the drift rate should be negative when current_fixation == 0 for example in the follow script. If I am not adding the negative sign, I get some weird results of parameter estimates (such as d=0 or theta = 0 or 1). It would be great if you can share some insight here.

Best regards,
Jiashun

You're right, thanks for the bug report! Fixed in the documentation with commit cf1eb2d.
