good tutorial/textbook chaper/review paper on Poisson regression :

Below are a few readings that discuss how to fit a generalized linear mixed model.

1. Breslow & Clayton (1993), JASA, Approximate Inference in
Generalized Linear Mixed Models.
https://doi.org/10.2307/2290687
A classic statistical paper introducing the Laplace approximation and penalized quasi-likelihood for GLMMs

2. Bates (2011), Mixed models in R using the lme4 package Part 5: Generalized linear mixed models
https://lme4.r-forge.r-project.org/slides/2011-03-16-Amsterdam/5GLMMH.pdf 3. Bates, D., Mächler, M., Bolker, B., & Walker, S. (2015). Fitting linear mixed-effects models using lme4. Journal of statistical software, 67, 1-48.
https://doi.org/10.18637/jss.v067.i01
4. Bates (2025), Computational methods for mixed models
https://cran.r-project.org/web/packages/lme4/vignettes/Theory.pdf

These are written by the authors of the lme4 package, discussing the details of how a mixed-effects model (more specifically, a generalized linear mixed-effects model) is trained using the PIRLS approach.

Master Equation Notes – Following Up on Your Questions

February 22, 2026

1. Paulsson (2005) – “Models of stochastic gene expression”
https://www.sciencedirect.com/science/article/abs/pii/S1571064505000138 Nice pedagogical review of the master equation framework – covers the conceptual foundations and different analytical approaches.

2. Shahrezaei & Swain (2008) – “Analytical distributions for stochastic gene expression”
https://pubmed.ncbi.nlm.nih.gov/18988743/
This one derives the exact analytical solutions to the master equation for protein/mRNA distributions.

The Paulsson paper is probably better as a tutorial.
However, it’s a bit difficult to connect to protein & mRNA.

QT:{{”
Reinforcement learning or RL is a class of methods for solving various kinds of sequential decision making
tasks. In such tasks, we want to design an agent that interacts with an external environment. The agent
maintains an internal state zt, which it passes to its policy π to choose an action at = π(zt). The environment
responds by sending back an observation ot+1, which the agent uses to update its internal state using the
state-update function zt+1 = SU(zt, at, ot+1). See Figure 1.1 for an illustration.
To simplify things, we often assume that the environment is also a Markovian process, which has internal
world state wt, from which the observations ot are derived. (This is called a POMDP — see Section 1.2.1).
We often simplify things even more by assuming that the observation ot reveals the hidden environment state;
in this case, we denote the internal agent state and external environment state by the same letter, namely
st = ot = wt = zt. (This is called an MDP — see Section 1.2.2). We discuss these assumptions in more detail
in Section 1.1.3.
RL is more complicated than supervised learning (e.g., training a classifier) or self-supervised learning
(e.g., training a language model), because this framework is very general: there are many assumptions we can
make about the environment and its observations ot, and many choices we can make about the form the
agent’s internal state zt and policy π, as well the ways to update these objects as we see more data. We
will study many different combinations in the rest of this document. The right choice ultimately depends on
which real-world application you are interested in solving.1 .”}}
