Predicción de cotizaciones anuales promedio de los principales minerales explotados en Bolivia, para el periodo 2014-2024
Abstract
La industria minera es una de las más importantes en el país; por ello, exige bastante atención desde el punto de vista científico y tecnológico. La vida de un proyecto minero fácilmente supera los veinte años, el periodo de tiempo desde el momento en el que una campaña de exploración verifica la existencia de un cuerpo mineralizado explotable y el inicio de la explotación misma puede fácilmente, dependiendo del tamaño del depósito mineralizado, sobrepasar los cinco o diez años. En otras palabras, si hoy decidimos explotar un cuerpo mineralizado, la explotación misma se iniciará en cinco a diez años. Esto significa que es absolutamente necesario estimar o predecir cotizaciones y costos para periodos de tiempo considerables, diez o veinte años. Por ello es importante desarrollar modelos de predicción propios y utilizar los mismos para predecir en este caso, cotizaciones de los minerales que se explotan en el país (Au, Ag y Sn). Hay varias alternativas para construir modelos de predicción de cotizaciones de minerales; desde complejos modelos econométricos de predicción hasta modelos simples basados en su análisis de tendencia. El concepto de análisis de tendencia es ajustar una línea de tendencia, utilizando el análisis de regresión o las series de tiempo a datos históricos de la cotización del mineral de interés. Este método puede a menudo proporcionar una primera buena aproximación de cotizaciones futuras. Los métodos econométricos de predicción de cotizaciones implican la modelización de las interrelaciones entre la oferta, la demanda y elementos de costos de uno a más minerales. El presente trabajo propone construir modelos de predicción de cotizaciones para los minerales Au, Ag y Sn. En cada caso se efectuará un análisis de tendencia además de proponer un modelo econométrico. Se utilizarán ambos modelos para predecir las cotizaciones anuales promedio de los minerales anotados para el periodo 2014-2023. Se validará cada uno de los modelos y se recomendará el más conveniente para el propósito anotado.

The life of a mining project easily exceeds twenty years, the period of time from the moment in which an exploration campaign verifies the existence of an exploitable mineralized body and the beginning of the exploitation itself can easily, depending on the size of the mineralized deposit , exceed five or ten years. In other words, if today we decide to exploit a mineralized body, the exploitation itself will begin in five to ten years. This means that it is absolutely necessary to estimate or predict quotes and costs for considerable periods of time, ten or twenty years. Therefore, it is important to develop our own prediction models and use them to predict in this case, prices of the minerals that are exploited in the country (Au, Ag and Sn). There are several alternatives to build prediction models for mineral quotes; from complex econometric prediction models to simple models based on their trend analysis. The concept of trend analysis is to adjust a trend line, using regression analysis or time series to historical data of the price of the mineral of interest. This method can often provide a good first estimate of future quotes. Econometric methods of price prediction involve modeling the interrelationships between supply, demand and cost elements from one to more minerals. The present work proposes to build quotation prediction models for the Au, Ag and Sn minerals. In each case a trend analysis will be carried out in addition to proposing an econometric model. Both models will be used to predict the average annual prices of the minerals listed for the 2014-2023 period. Each of the models will be validated and the most convenient for the purpose noted will be recommended
