EVALUATION OF HAITIAN AGRICULTURAL DEVELOPMENT WITH THE USE OF PRINCIPAL COMPONENTS
以海地Bas Boen地区项目为例，使用主成分分析法建立生产响应与推广投入之间的关系，帮助评估农业开发项目的整体绩效。
Considerable experimental agricultural development efforts have been undertaken in Haiti (Zurekas, 1978, pp. 80–120). Many of the Haitian programmes have been directed toward development through intensive extension efforts with the primary purpose of providing local producers with improved production and management techniques. Frequently such experiments are localised and designed to emphasise the development methods while giving less consideration to evaluating the overall project performance. The Haitian Bas Boen region development project is a case in point (Prires, 1978, p. 76). In this paper the Bas Boen project is considered with the primary objective to show the relationship between production responses to intensive agricultural development programmes. A statistical technique using principal components is used to link production responses to those inputs changed through the extension efforts.
