英文摘要:
Farmers use pesticides to reduce yield losses. The efficacies of pesticide treatments are often evaluated by analyzing the average treatment effects and risks. The stochastic efficiency with respect to a function is often employed in such evaluations through ranking the certainty equivalents of each treatment. The main challenge of using this method is gathering an adequate number of observations to produce results with statistical power. However, in many cases, only a limited number of trials are replicated in field experiments, leaving an inadequate number of observations. In addition, this method focuses only on the farmer\'s profit without incorporating the impact of disease pressure on yield and profit. The objective of our study is to propose a methodology to address the issue of an insufficient number of observations using simulations and take into account the effect of disease pressure on yield through a quantile regression model. We apply this method to the case of strawberry disease management in Florida.

中文摘要:
农民使用杀虫剂来减少产量损失。农药治疗的效果通常通过分析平均治疗效果和风险来评估。在此类评估中,通常通过对每种处理的确定性等价物进行排序,来使用函数的随机效率。使用这种方法的主要挑战是收集足够数量的观察结果,以产生具有统计能力的结果。然而,在许多情况下,现场试验中重复的试验数量有限,留下的观察数量不足。此外,这种方法只关注农民的利润,而没有考虑疾病压力对产量和利润的影响。我们研究的目的是提出一种方法,通过模拟解决观测数量不足的问题,并通过分位数回归模型考虑疾病压力对产量的影响。我们将此方法应用于佛罗里达州草莓病害管理的案例。
