Comparison of regression models of linear and polynomial dependencies in moisture detection technique

Abstract

The article presents the description of moisture detection technique in building materials and comparison of two techniques of analysis. More precisely, two models of linear regression, with linear and polynomial dependencies are presented. The readouts present the dependence between the moisture of ceramic brick, evaluated gravimetrically and permittivity values determined by TDR technique. The correlation between the moisture content estimated by the TDR and the moisture content determined gravimetrically is shown. Using the achieved data, regression models are compared and the quality of both models is determined.
