Kenya’s horticulture sector is one of the key contributors to country’s national income. In this paper, we apply Box-Jenkins SARIMA time series modeling approach develop a model that best describes income economy from export produce. process analysis, considered monthly data August 1998 March 2023. It was found that, SARIMA(3; 1; 4)(0; 0)12 suitable

We consider the forecasting of cointegrated variables, and we show that at long horizons nothing is lost by ignoring cointegration when forecasts are evaluated using standard multivariate forecast accuracy measures. In fact, simple univariate Box-Jenkins forecasts are just as accurate. Our results highlight a potentially important deficiency of standard forecast accuracy measures—they fail to v...

Beef and cattle milk production play a significant role in reducing hunger, malnutrition, rural poverty, improving livelihoods, creating employment opportunities, supporting the overall development of Uganda's economy. This study was conducted to find suitable ARIMA model for forecasting Uganda’s beef using annual time series data from 1961 2020, extracted Food Agriculture Organization Corporat...

General aspects of modeling as an engineering tool are presented in this work. The usefulness of Takagi-Sugeno Fuzzy Inference Systems (TS FIS) as modeling technique are emphasized. Additionally, various modifications of known methodology for identifying such a models and rules configuration are proposed. Finally, two application examples are presented. The first one is a modeling of the Box an...
