I1 Mean-Change Testing and DCI Candidate Detection R package DCIi1 version 0.2.0 Computes the I1 statistic for mean changes and generates multiple candidate change locations using adaptive contrasts and local interquartile scaling. Provides empirical I1 p-values for independent Gaussian series of length 100 with full-window parameter 22, statistic-only analysis for other settings, and weighted and unweighted segmentation covering scores. DCI candidate detection is descriptive and does not assign significance to selected segments. Based on the methodology of Waychal, Laha and Sinha (2026) <doi:10.48550/arXiv.2610.23476>.
