在Python中，Theil-Sen Median斜率估计和Mann-Kendall趋势分析是两种常见的数据分析工具，它们常用于探究长期数据集如多年NPP或NDVI的趋势。Theil-Sen斜率估计是一种非参数回归方法，通过计算所有数据点对斜率的中位数，提供对趋势斜率的稳健估计，特别适合处理包含异常值的数据，因为它使用的是中位数而非均值...
Theil-Sen Median方法，也称为Sen斜率估计，是一种稳健的非参数统计方法，它对测量误差和离群数据不敏感...

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 outliers as it uses themedian as a measure of central tendency instead of the mean. This helps to avoid the influence of extreme values ...

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 ...
A second extension of the Theil-Sen estimator, based on a direct estimation of the median of pairwise slopes, is given. These estimators are compared numerically with versions of Schmitt's estimator and applied to two data sets from the recent astronomical literature....
