介绍一下Theil-Sen Median斜率估计和Mann-Kendall趋势分析,这两种方法经常结合使用,前者用于估计趋势的斜率,后者用于检验趋势的显著性。如多年NPP或者NDVI的趋势分析。 Theil-Sen斜率估计Theil-Sen回归是一种鲁棒线性回归方法,用于减小异常值对拟合结果的影响。与最小二乘法和一些其他回归方法不同,Theil-Sen回归使用了一...
4. Calculate the median slope: For each pair of differences in the dependent and independent variables, calculate the slope and store it. Then, find the median of all these slopes. The Theil-Sen estimator has several advantages over other linear regression methods. Firstly, it is robust to ou...
In addition to finding the median slope, you’ll also want to create a confidence interval for that slope. By hand, confidence intervals can be somewhat cumbersome; they become more challenging to calculate for non-normal distributions (which is what is involved with Theil-Sen estimators) and ...
the Theil–Sen estimator, also known as Sen's slope estimator,slope selection,the single median method, or the Kendall robust line-fit method, is a method for robust linear regression that chooses the median slope among all lines through pairs of two-dimensional sample points. It is named ...
