## Abstract

In this paper we study Monte Carlo estimators based on the likelihood ratio approach for steady-state sensitivity.   We first extend the result of Glynn and Olvera-Cravioto \[doi:doi: 10.1287/stsy.2018.002\] to the setting of continuous time Markov chains with a countable state space which include models such as stochastic reaction kinetics and kinetic Monte Carlo lattice system.   We show that the variance of the centered likelihood ratio estimators does not grow in time. This result suggests that the centered likelihood ratio estimators should be favored for sensitivity analysis when the mixing time of the underlying continuous time Markov chain is large, which is typically the case when systems exhibit multi-scale behavior. We demonstrate a practical implication of this analysis on a numerical benchmark of two examples for the biochemical reaction networks.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
