Asking to confirm my knowledge in R. When conducting SEM analysis, is it enough to report Robust indices to account for possible outlier detection or whether running Mahalanobis distance method (e.g.) still appears essential? Thanks in advance
In conducting SEM, you need to make sure that the assumptions of parametric test are met.
I have tried Trizol and Quiagen RNEasy kits to isolate RNA from waterfowl feces (I added influenza virus in serial dilutions to some feces samples as a positive control). However none of the...
