Stochastic models for the explanation of trend in production of rice in Kerala for the period 1957—1958 to 1971-1972

Abstract

Five different models were tried to explain the production of rice in terms of area (x), and period (0. The following results were obtained. A t yt = 946.2 x 1.022r with r = 0.80, y = 166.4 x 1 263* with i- = 0.84 A y ==287.9 x 1.172 X l.OOS1 with P ^ 0.84 A n O^RS^O t y{ := 925.47 . eU' with r = 0.64 and t A 0.032018 £ x. -0.231688 t with P = 0.66 yt = 925.47 . e 1 J The values of the coefficients of determination show that these models fit the data satisfactorily.
