Esta investigación, de enfoque mixto, se basó en la predicción de la evolución de la cartera de créditos a PYMES en Ecuador. Se utilizó el modelo Holt-Winters y la red Extreme Learning Machine, que combinan modelos econométricos y redes neuronales, acompañados del análisis geoespacial a nivel de provincias. El modelo presentó ajuste óptimo de los datos reales, comprende eficazmente el 93 % de la variabilidad de estos, muestra un eficiente pronóstico y rendimiento ligeramente superior sobre otros modelos analizados. Este resultado es crucial para la toma de decisiones y la planificación de los recursos financieros destinados a las PYMES ecuatorianas.
