Enter precipitation values separated by commas, spaces, tabs, or new lines. The calculator sorts them and calculates the sample L-moment estimators used for L-mean, L-CV, L-skewness, and L-kurtosis.
1. Enter CAM grid-cell values
2. Final estimates
L-mean · L₁
L-CV · τ₂
L-skewness · τ₃
L-kurtosis · τ₄
3. Sorted values
4. Rank weights and weighted contributions
The first column is the sorted CAM value. The next columns show the exact rank weights used to build b₁, b₂, and b₃.
Rank i
x(i)
b₁ weight
x·w₁
b₂ weight
x·w₂
b₃ weight
x·w₃
5. Probability-weighted averages
6. Convert them into L₁ through L₄
7. Normalize the shape statistics
SLAM interpretation: L₁ is overall CAM magnitude. L-CV describes spatial spread relative to the mean. L-skewness describes asymmetry. L-kurtosis describes upper-tail/shape behavior.
