ctmaEqual {CoTiMA} | R Documentation |
test if the two or more invariant drift parameters in the CoTiMAFit object supplied are equal. The supplied CoTiMA fit-object
(ctmaInvariantFit) has to be a model fitted with ctmaFit
where at least two parameters were set invariant across primary studies (e.g., 2 cross
effects). All parameters that are set invariant in the supplied model are then constrained to be equal by ctmaEqual (no user action
required), the model is fitted, and a log-liklihood ratio test is performed informing about the probability that equality applies.
ctmaEqual( ctmaInvariantFit = NULL, activeDirectory = NULL, activateRPB = FALSE, digits = 4, coresToUse = 1 )
ctmaInvariantFit |
object to which a CoTiMA fit has been assigned to (i.e., what has been returned by |
activeDirectory |
defines another active directory than the one used in ctmaInvariantFit |
activateRPB |
set to TRUE to receive push messages with CoTiMA notifications on your phone |
digits |
Number of digits used for rounding (in outputs) |
coresToUse |
If neg., the value is subtracted from available cores, else value = cores to use |
returns a model where two or more parameteres were set equal across primary studies and a log-liklihood difference test informing about the probablity that the equality assumption is correct.
