Fitting of Statistical Models for Paddy Crop Area of Selected Districts of Karnataka after BIAS Correction

摘要

The BIAS correction is done based on 17 years (1998-2015) data on area and production for Paddy crop at selected districts of Karnataka such as Bellary, Davangere and Raichur. The study revealed that MDM recorded least value of normalized root mean square error (NRMSE) for paddy crop area in all the selected districts compared to DM method. Auto correlation was found to be absent in corrected paddy crop area of all the selected districts. Thus, Model fitting was done using linear and nonlinear modelsand the results showed that cubic model was the best fit with high R2, Adj. R2 and least root mean square error (RMSE) value for all the districts.
