【摘要】 针对农药生物活性测定,作者建立了加权相关模型。与最小二乘回归及其加权模型、相关模型相比较,该方法综合考虑了两维方向误差,所确定的加权相关模型不会因x和y的选取而改变,结果较为客观,且精度较高,可作为农药生物活性测定的校正方法。更多还原

【Abstract】 For applying to testing biological activity of pesticides,the weighted-dependent least squares model is proposed.It is different from the traditional least squares model and its weighted-model,dependent- model.The weight and errors of two directions are comprehensively considered during setting a new model,so that this model is unchangeable with x-y’s direction,the result is more objective and the accuracy is better.It may be considered as a correcting way for testing biological activity of pesticides.更多还原
