WebApr 12, 2024 · Antiretroviral therapy (ART) has improved survival and clinical course amongst HIV/AIDS patients. CD4 cell count is one of the most critical indicators of the disease progression. With respect to the dynamic nature of CD4 cell count during the clinical history of HIV/AIDS, modeling the CD4 cell count changes, which represents the likelihood … WebA (first order) Markov model represents a chain of stochastic events, in which the probability of each event transition depends only on the state reached of the previous event. So, there is no “memory” beyond the previous event. The chain of successive events is called a Markov process, which is continuous, if transitions can occur any time, or discrete when this is …
