Multivariate calibration transfer employing variable selection and subagging

Abstract: Neste artigo, é proposta uma nova técnica para transferência de calibração, que combina o Algoritmo das Projeções Sucessivas (APS) para seleção de variáveis robustas com a técnica de sub-amostragem e agregação de modelos conhecida como subagging. A técnica proposta tem por objetivo construir modelos de Regressão Linear Múltipla (RLM) que sejam robustos com respeito a diferenças na resposta instrumental de dois espectrômetros (primário e secundário). Para isso, um pequeno conjunto de amostras de transferência, … Show more

“…In both investigations, 12,14 this ratio was arbitrarily set to approximately 60% (number of calibration samples/number of calibration plus validation samples). The present paper investigates the effect of the subsampling ratio on the resulting MLR-SPA-subagging model.…”
