Liu等(2024)利用Theil-Sen Median斜率估计和Mann-Kendall趋势分析对沉积物连续性指标(IC)1990-2020年间30年的变化趋势进行了分析 一般来说,可以根据Theil-Sen Median计算出的β值和Mann-Kendall计算出的Z值进行趋势分类 在Theil-Sen Median斜率估计和Mann-Kendall趋势分析:以多年NPP数据为例这篇博客中提到了具体的分...
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...
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...

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 ...
Similarly, the median of the y-intercepts corresponding to these pairs of points is the estimated intercept of the regression line. Here's how the Theil-Sen regression works: 1. For each pair of data points (xi, yi) and (xj, yj) in the dataset, calculate the slope (b) and intercept...
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 ...
In addition to finding the median slope, you’ll also want to create aconfidence intervalfor that slope. By hand, confidence intervals can be somewhat cumbersome; they become more challenging to calculate fornon-normal distributions(which is what is involved with Theil-Sen estimators) and whenhomo...
