do cfa modifications have to be covariate or indepenent if indepenent variable and independent variable can i make a new path between independent variable (in) and error term and indepenent variable (PU)? if a fit indices is good, what is the problem? when to use modification indices cfa definition of error term if a variable is a covariant and an indepenent variable, can this result in a good fit? can you covariate independent variable and indepenent variable? can you covariate an error term and a composite variable what model is orange lines can i covarigate the error term of a second mediator of a modified model? can i use modification indices to test a model of fitness can i appoint a composite variable in the coma model why can't i covariate in modified indices how to prove an error in a sem model can you covariate a variable and an indepenent variable in cfa can an independent variable be a composite variable in a modified model why does a fit indices curve can i covariate a variable in modification and a second mediator when a model is modified a fit indice is made.
