In the unscaled case, the line shapes of PC loadings are interpretable because a loading value is proportional to the SD of a spectral variable σk, which is, respectively, lower and higher for variables that constitute minor and major intensities of a peak.
Factor 2 explains 19.85 % of the total variance and shows high positive loadings for total alkalinity, magnesium and bicarbonate, an average loading value for sodium and a negative loading score for calcium.
All of the model parameters of this one-factor model were significant at the p < 0.05 level, and the standardized factor loadings ranged from 0.29 to 0.83, with the lowest loading value being for item 15 ("Feeling dissatisfied with your diabetes physician").
Then, the factor analysis was conducted to calculate the factor loading value and to find out whether there exists cross-loading among items.
A principal components (metabolites) selection criterion for diabetic and non-diabetic group discrimination was set for components with loadings (i.e., variance contribution) ≥1 standard deviation from the mean loading value in each of the discriminating PC2 and PC3 dimensions.
In reporting the reactions whose loadings dominated or defined unrotated and rotated eigenvectors, we report any reaction whose loading value is at least half of the largest absolute loading value of the eigenvector.
The loading value was measured with a load-cell attached to the tensile test machine.
Each question attained validity with a factor loading value of.70 or more.
For example analytes with a loading value of zero are not correlated with any other analyte.
There is moreover a critical loading value above which the capacity retention abruptly drops.
The effect of loading value and location on radial strain and hoop strain were studied.
