“…Research on estimating the expected value function and variance function in a compound periodic Poisson process with a linear function trend has been reported in (Wibowo et al, 2017) and (Abdullah et al, 2017). Several related studies can be found in (Mangku et al, 2016) and (Prasetya et al, 2017), and estimators of the expected value function and variance function on a compound periodic Poisson process with a power function trend have been reported in (Sari et al, 2016) and (Fajri, 2018). Furthermore, to find the asymptotic distribution of the compound periodic Poisson process variance function estimator with a power function trend, it is necessary to modify the variance function estimator to make it easier to find the distribution.…”
