Imputación de Datos en Series de Precipitación Diaria Caso de Estudio Cuenca del Río Quindío

Abstract: En este artículo se presentan los resultados obtenidos por la aplicaciónde cinco técnicas de imputación de datos en series de precipitación diaria para ocho estaciones que tienen aferencia sobre la cuenca del río Quindío, localizada en la zona central colombiana.  Con el propósito de preservar la generación de valores de precipitación igual a cero, se consideró el cálculo de probabilidades empíricas a partir de una cadena de Markov de primer orden. Las técnicas fueron implementadas en un algoritmo itera… Show more

“…The existence of negative spatial autocorrelation may be a major limitation in the application of IDW for estimating missing data. Moreover, climate models, as a useful approach for filling rainfall data, are limited by their spatial scales, cost of model development, and computational burden (Reinoso 2016). Owing to the limitations of traditional statistical methods in handling nonstationary issues and in choosing only nearby stations for predicting rainfall data, the search for an accurate method is still ongoing.…”

“…However, despite their utility, satellites provide limited coverage and, in most cases, they have very coarse resolutions that limit local applications. Similarly, climate models are useful but are limited by their spatial scale and are often quite expensive to be developed (Reinoso, 2016). Methods of artificial intelligence, such as artificial neural networks (ANN) and support vector machines (SVM) (Mileva-Boshkoska and Stankovski, 2007;Mwale et al, 2012;Hasan et al, 2015) have a complex mathematical formulation.…”
