tidexcorr: A lag-regression framework for reconstructing sparse or short water-level records from neighboring gauges

tidexcorr implements a lag-regression framework for reconstructing sparse, short, or discontinuous water-level records from neighboring gauges. The method preserves physical consistency and supports long-term analysis, data quality control, and extreme-event characterization in estuarine, coastal, and inland systems. The source code implements the lag-regression framework presented in: Matte, P., Innocenti, S., 2026.
