Relationships of climatic variables and cacao theobroma cacao production of the unit farm of the cacao research center bahia brazil



Relationships of climatic variables and cacao theobroma cacao production of the unit farm of the cacao research center bahia brazil



Revista Theobroma 14(2): 143-148



The cacao production-weather relationships of a farm were studied in 1970-1981. Linear correlations between the monthly cacao production and different climatic factors lagged in time. In addition, linear correlations between the cacao crop and climatic factors observed monthly of a year earlier were studied. A set of 8 climatic variables represented by climatic factors or linear combinations of these was chosen by maximum correlation. The best subset of these variables in regression was selected. The criteria for determining the best subset regression were the maximum determination coefficient (R2), maximum adjusted coefficient and the Cp statistics of Mallows minimum.
