Dear Pymc3 experts, I am trying to use a cognitive model called RDM(racing diffusion model) in pymc3 and I confront some problems. Racing diffusion model is quite similar to the linear ballistic accumulator model, assuming the number of evidence accumulators is identical to the option number. The b…

Given that the invalid values are x_left and y_left (which seem like they may be misnamed?), it seems as though the problem is either the rdm_wfpm object or, more likely, the values that are being passed into it’s constructor. It looks as though you have opened an issue about this on the glambox GH…

Yeah, I misnamed these two variables. Thank you for your response. Yeah, it’s my post.

BTW, recently I asked lots of stupid and naive questions, I noticed that you answered many of them. Thank you for this, really appreciate it.
