- Abstract
This study deals with the application of classical time series models such as double moving average method, exponential smoothing (Brown's double exponential smoothing method and Holt's double exponential smoothing method) along with neural network autoregression model for rice yield prediction in Karnal district of Haryana (India). The district annual time series data on rice productivity were divided into the training data set from 1980-81 to 2013-14 and the test data set from 2014-15 to 2019-20. Among the models fitted, the neural network model had a significantly lower absolute error and the root mean square error. During the test period, a markedly low mean absolute percent deviation was observed for the moving average (7×7) model. However, Future forecast values by this model surpass a fair threshold for rice yield in the country. Considering both the error analysis and model validation results it is found that neural network forecasting models are best fit for forecasting of rice yield in Karnal district followed by Holts double exponential method.
