Correlation Analysis of Textile Property Relationships
topic
Pearson correlation coefficient quantifies the linear association strength and direction between pairs of normally distributed textile properties including yarn tenacity and elongation, fabric weight and air permeability, and colour strength and dye concentration, while partial correlation isolates pairwise relationships controlling for the confounding influence of additional measured variables.
Role
Identifies the empirical relationships between textile properties that guide understanding of structure-property relationships, enables prediction of difficult-to-measure properties from more accessible correlated measurements, and reveals potentially collinear predictors in regression models that require special handling to avoid inflated coefficient variance.
