Present investigation was an attempt to study the trend of jute production in West Bengal for the period starting from 1950 to 2016. For stochastic trend estimation, a number of time series parametric regression models viz. Linear model, Quadratic model, Exponential model, Logarithmic model, Power model and Auto Regressive Integrated Moving Average (ARIMA) were employed and compared for finding out an appropriate econometric model to capture the trend of jute production of the country. Based on the performance of several goodness of fit criteria viz. Root Mean Squared Error (RMSE), Mean Absolute Percentage Error (MAPE), Mean Absolute Error (MAE), and R-squared values best fitted model was selected. The assumptions of ‘Independence’ and ‘Normality’ of error terms were examined by using the ‘Run-test’ and ‘Kolmogorov-Smirnov (K-S) test’ respectively. This study found ARIMA (1, 1, 2) as most appropriate to model the jute production of West Bengal. The forecasted value by using this model was obtained as 9149.22 (In ' 000 Bales of 180 Kgs. each) by 2021.
