In the past, most threshold models considered a single variable. However, for some practical applications, with two variables may be needed. this paper, we propose two-threshold-variable integer-valued autoregressive model based on binomial thinning operator and discuss of its basic properties, including mean, variance, strict stationarity, ergodicity. We consider conditional least squares (CLS...

Introduction Abnormal neural impulses in the nervous system may lead to various diseases and disabilities. High frequency alternating currents (HFAC) has been used to block the propagation of such impulses and improve the symptoms or disabilities. The technique is safe, reversible, and relatively selective, and its reliability, the optimum stimulation parameters, and elimination of the onset re...
