%description
Implements Cumulative Sum (CUSUM) control charts specifically designed for
monitoring processes following a Gamma distribution. Provides functions to
estimate distribution parameters, simulate control limits, and apply
cautious learning schemes for adaptive thresholding. It supports upward
and downward monitoring with guaranteed performance evaluated via Monte
Carlo simulations. It is useful for quality control applications in
industries where data follows a Gamma distribution. Methods are based on
Madrid-Alvarez et al. (2024) <doi:10.1002/qre.3464> and Madrid-Alvarez et
al. (2024) <doi:10.1080/08982112.2024.2440368>.
