Moreover, in order to improve the fit of the three structural models to empirical data, some variables (and the related paths and parameters) that were worth the effort of re-specification were withdrawn according to indexes of modification (e.g., standardized residues of the covariance matrix).
Specifications include indexes of modification, kernel plumpness, friability (friable grain is easier to mill), protein content as well as free amino nitrogen (FAN) content, enzyme activity or content, and moisture content.
The outlined procedure in this study may be more sensitive to detect "truly" non-invariant items, because the magnitude of the EPC and the power of modification indices are taken into account.
Overall, moderately fragmented landscapes and those surrounded by matrices with intermediate indexes of temporal modification (i.e., crop plantations, forestry) are related to high densities of this species.
To test this hypothesis we compared cerebellar oxidative stress markers 3-nitrotyrosine (3-NT; an index of oxidative protein modification) and 8-hydroxy-2′-deoxyguanosine (8-OH-dG; an index of oxidative DNA damage) between stationary control (SC) and rat neonates exposed to 1.65 G (HG) on a 24-ft centrifuge from gestational day (G) 8 to postnatal day (P) 21.
Furthermore, the conclusion drawn by the analysis must take the power of the modification index test into account, which can be computed for every combination of modification index, EPC, δ and significance level alpha (which was fixed at alpha = 0.05 in this study).
Recently, in order to increase refractive index of organic polymers, surface modification methods, such as deep UV modification and ion-beam implantation, have been reported [22, 23].
The examination of modification indices showed no evidence of error correlations.
An inspection of modification indices helped identifying the cause of misfit: a residual correlation between items 1 and 2 of the R dimension, which have similar content.
