LMDT measures\nthe spectral smoothness (Dirichlet energy) of robust\nlog-dispersion residuals over a self-tuning k-nearest neighbors\ngraph Laplacian, as formulated in Jabbar (2026). The test\nstatistic is asymptotically distribution-free with respect to\nerror kurtosis and accommodates high-dimensional covariates (p\n> 50) via Gavish-Donoho optimal hard thresholding and\nsupervised metric learning.", "License": "GPL (>= 3)", "URL": "https://amjed-droid.github.io/LMDT/,\nhttps://github.com/amjed-droid/LMDT", "BugReports":
