The fixpar function can be used to fix a parameter to some value (Typically zero), and the freepar function can be used to free a parameter from being fixed to a value.
fixpar(x, matrix, row, col, value = 0, group, verbose,
log = TRUE, runmodel = FALSE, ...)freepar(x, matrix, row, col, start, group, verbose, log =
TRUE, runmodel = FALSE, startEPC = TRUE, ...)
An object of the class psychonetrics (psychonetrics-class)
A psychonetrics model.
String indicating the matrix of the parameter
Integer or string indicating the row of the matrix of the parameter
Integer or string indicating the column of the matrix of the parameter
Used in fixpar to indicate the value to which a parameters is constrained
Used in freepar to indicate the starting value of the parameter
Integer indicating the group of the parameter to be constrained
Logical, should messages be printed?
Logical, should the log be updated?
Logical, should the model be updated?
Logical, should the starting value be set at the expected parameter change?
Arguments sent to runmodel
