ANALYSIS OF VARIANCE WITH FUNCTIONAL DATA TO DETECT COLOR CHANGES IN GRANITE

Abstract

Analysis of spectral reflectance curves is useful in many application fields. Despite the functional nature of these curves, statistical methods used to date for analysing these curves (classification, analysis of variance, etc.) have tended to be scalar and do not fully take advantage of the information they contain as functional objects. In this article we applied functional analysis of variance to spectral reflectance curves in order to evaluate the impact of protective treatments on granite colour. The use of raw information on the spectrum means that significant changes are detected that might go unnoticed in models that use scalar values to measure colour. The application of the funcional approach enables information to be obtained on changes whose intensity are statistically significant at each point of the spectrum without the need to perform different analyses for each area of the spectrum. Furthermore, the computational load is no greater than for classical multivariate models.
