The present study is an attempt to find past trends of apple in Jammu and Kashmir using parametric, nonparametric and semi-parametric regression methods. The performance of each method is compared using higher values of R2 and lower values of residual criteria. It is found that the nonparametric/semi-parametric regression comes out to be good fit for trends in apple production in comparison to the parametric regression. | Utilization of parametric and nonparametric regression models for production, productivity and area trends of apple (Malus domestica) in Jammu and Kashmir, India
