Regression Estimation of Crop Acreages With Transformed Landsat Data as Auxiliary Variables
开发了将卫星数据与地面调查数据结合的方法，用于估计作物面积，比较了两种卫星信息变换方法在回归估计中的效果。
Abstract Methods are developed for combining data collected by satellite with data collected in an area survey to estimate crop acreages. The basic procedure is that of survey regression estimation. Two methods of transforming the satellite information prior to regression estimation are compared. KEY WORDS: Sample surveyJackknife
