Non‐homogeneous continuous‐time Markov chain with covariates: Applications to ambulatory hypertension monitoring
Sign Up to like & getrecommendations! Published in 2023 at "Statistics in Medicine"
DOI: 10.1002/sim.9707
Abstract: Hypertension significantly increases the risk for many health conditions including heart disease and stroke. Hypertensive patients often have continuous measurements of their blood pressure to better understand how it fluctuates over the day. The continuous‐time… read more here.

DOI: 10.1016/j.apm.2018.05.009
Abstract: Abstract We consider the approximation of transient (time dependent) probability distributions of discrete-state continuous-time Markov chains on large, possibly infinite state spaces. A framework for approximate adaptive uniformization is provided, which generalizes the well-known uniformization… read more here.
