In gSeg: Graph-Based Change-Point Detection (g-Segmentation)

gSeg 1.1

• Added data-level gseg1_data() and gseg2_data() interfaces.
• The data-level interfaces use a k-MST with k = floor(sqrt(N)) by default.
• Default calls report MET. GET, OET, and WET remain available through the explicit statistics = "g", "o", or "w" options, or together through statistics = "all".
• Existing graph-level interfaces remain available.
• Monte Carlo permutation p-values use the standard plus-one correction.
• Corrected changed-interval permutation output so that it retains one scan maximum per permutation and uses all B maxima to compute the p-value.
• Added explicit checks for analytic small-sample limits, degenerate graphs, duplicate edges, and malformed inputs.
