R spuckt mit bei meinem Modell gute Fit-Werte raus, allerdings sind die Ladungen sehr gering. Weiß jemand was mögliche Gründe dafür sein könnten? Es handelt sich um 0-1 Kodierungen der Items.
aufgrund Deiner Angaben, Hilft nur der Blick in die Kristallkugel! Such doch einfach mal in diesem Forum nach CFA!
Viele Grüße,

Ok, das würde ich an Deiner Stelle jetzt wahrscheinlich auch behaupten.
Vielleicht kann man einer sehr allgemeinen Frage wenigstens zwei sehr allgemeine Antworten entgegen halten:
It should be noted that a good-fitting model is not necessarily a valid model. For instance, a model all of whose estimated parameters are not significantly different from zero is a "good-fitting" model. Conversely, it should be noted that a model all of whose parameters are statistically significant can be from a poor fitting model. Additionally, models with nonsensical results (e.g., paths that are clearly the wrong sign) and models with poor discriminant validity or Heywood cases can be “good-fitting” models. Parameter estimates must be carefully examined to determine if one has a reasonable model.
Super important caveat
If your model fits well, that does NOT necessarily mean it is a “good” model, or that it reflects truth or reality well. In CFA even more so than other kinds of statistical modeling, the theory behind your model is crucial to deciding whether or not a model is any good. If you start playing around with SEM, you’ll quickly realize that for a given set of variables, there are often many different models that fit well, and they may even seriously contradict each other and/or suggest nonsensical relationships. Good model fit does not make a good model.
