I have RT-Accuracy data. I want to estimate the parameters of a drift diffusion model (Ratcliff, 1978). I am assuming that:

v(t)=v(t-1) + v + e(0,s). meaning that at each giving time evidance is accumulated from a normal distribution with expected value v and noise s. I am very very new to R. I installed rtdists. can some one pls explain/refer me as to how I use this package (or any other) to estimate the Drift Diffusion parametes? thanks a lot. Ariel
