Collinearity diagnostics were evaluated to ensure independence of the independent variables.
The emphasis in this section is mainly on introducing some concepts such as credibility measure, credibility space, fuzzy variables, independence of fuzzy variables, expected value, variance, fuzzy process, Liu process, and stopping time.
To explore risk factors for HAI caused by antimicrobial resistant versus susceptible A. baumannii strains, bivariate analyses between infection and possible predictors were conducted using Pearson's χ test for independence (categorical variables) or simple logistic regression (continuous variables).
Demographic characteristics were investigated using the Chi-square test for independence (nominal variables) and analysis of variance (ANOVA) (continuous variables) followed up by Bonferroni post-hoc tests for group comparisons when adequate.
Independence of variables is determined by whether or not another variable is a direct descendent in the DAG representation [47].
Specifically, for each query about the statistical independence between variables a and b given a set of variables S and, implicitly, the genetic effects: a) Obtain the posterior distribution of residual partial correlation ρ a,b | S.
Here, we show the effect of independence of variables on the utility functions and later consider dependence and independence of variables in the examples of Sect. 3.
An exploratory correlation coefficient matrix of these nine variables showed that all were at most weakly associated (R2≤0.41), supporting the independence of variables, and enabling multiple regression (least squares method).
Independence between variables was determined before inclusion (r<0.5) and separate models used for collinear variables.
This is because FA just like principal component analysis (PCA) assumes an underlying linear independence of variables whose coefficients, also called "factors," are a proxy interpretation of AAindex variables [ 11].
On the other hand, the independence of variables used in linkage is often questionable, in which case the lower predictive ability of the individual variables is at the very least supportive of our conclusion.
