AMOS model fit indices are poor, but reliability and validity measures are fine?

24 September 2024 1 6K Report

In a scenario where AMOS model fit indices are poor (even after modifications), but reliability and validity (cronbach alpha, CR, AVE, discriminant validity) measures are at an acceptable level, could we bypass the model fit indices and report reliability and validity statistics to confirm the measurement model (CFA)? (assuming that data cleansing was conducted, no violation in normality)

Christian Geiser

No, because when model fit is poor, model-implied estimates of reliability and validity may be biased--they are based on an incorrect model.

How to extract intense rainfalls (e.g., annual maximum rainfall for 24-hr duration) from the historical records of daily rainfalls?

Generally, the daily rainfalls are recorded at fixed time intervals (e.g., from 9 am to 9 am). We can find such records of historical rainfalls for centuries. However, in such records, even the...
