Description Usage Arguments Details Examples
Simulate one or more responses from an EAM model object. This creates a data frame using the model.
1 2 3 |
object |
is a DMC model object. |
nsim |
nsim can be a single number for a balanced design or a vector (one number per cell) to create an unbalanced design. |
seed |
for compatible to stats simulate. Default NA |
p.vector |
a parameter vector. Use Lognromal LBA model as an example,
|
SSD |
is for use only with stop-signal designs, it must be a scalar, or a vector the same length as the number of cells or the same length as the data and have Inf in all go cells |
staircase |
is used only in stop-signal designs, overrides SSD, and simulates a tracking algorighm setting SSD=start initially then moving up step for each stop fail and down step for each stop-success. |
TRIALS |
is a trial number covariate used in stop-signal paradimgs to account for slowing or speeding over the course of the experiment. |

other arguments |
p.vector=ps[1,,drop=FALSE]; n=n[1,]; SSD=SSD[datr] !!! TO DO !!! !!! Add an update ability where n=data and RT is updated, also on first creation add index to speed update
