## The EZ-Diffusion Model

This is a small JavaScript program that computes the parameter values for
the EZ-diffusion model (for details consult the manuscript referenced at
the bottom of this page).
*Note*. If you have calculated the RT mean and RT variance based on
data measured in milliseconds, you need to take some care when transforming
these quantities to seconds. The RT mean in seconds is obtained from
the RT mean in milliseconds by simply dividing by 1000, but the RT variance
in seconds-squared is obtained from the RT variance in milliseconds by dividing by
1000 times 1000 (i.e., 1,000,000).
