Description
Estimates the drift rate, boundary separation, and
non-decision time for a two-boundary wiener process
with an equidistant starting point using a R function
adapted from Wagenmaker et al. (2007).
Usage
1
EZdiffusion(dat, s = 1)
Arguments
dat
a vector of inputs:
Total number of trials;
Number of correct responses;
Mean response time for correct responses;
Variance for corrct response times;
s
the scaling parameter (typically set to either 0.1 or 1)
Value
An estimate of the drift rate, boundary separation,
and non-decision time. Bias is fixed to 0.5.
