tau2tau  R Documentation 
Setting multiple process completion times (taus) equal. This means all process times of negative outcomes will be set equal and all process times of positive outcomes will be set equal. Only two process times (one for the negative and one for the positive outcome) of the named processes will be estimated. The equality can be removed by just naming only one process name.
tau2tau(model, names, outcome, keep_zeros = FALSE)
set_taus_equal(model, names, outcome, keep_zeros = FALSE)
model 
A list of the class 
names 
Character vector giving the names of the processes for which the process completion times should be equal. If

outcome 
Character (no vector) indicating for which process outcome the process completion times should be set equal. Allowed characters are:

keep_zeros 
Can be one of the following

A list of the class ertmpt_model
.
If you use theta2theta()
and tau2tau()
with the same process names you might just change the EQN or MDL file accordingly
by using the same process name for all processes which should have equal process times and probabilities.
