Maximum Likelihood Estimate of Infection Model Parameters
I'm using the standard infection model on some data I am working with.
$ dS = -\beta SI $
$ dI = \beta SI - \gamma I $
$ dR = \gamma I $
Where $S$ is the number of susceptible subjects, $I$ is the infected, and $R$ is the recovered. I'm trying…

How are epidemic models simulated in case of mobility?
I don't know whether this is a pure statistics, math or programming question so kindly let me know if there is a better place to post this question.
I am trying to implement the SIS epidemic model when the nodes have mobility. I understand how to…

Nearcasting disease spread: Why assume +1 immunized person per unit time?
I wouldn't normally consider the Stats SE to be the best place for this question, but neither the Medical Sciences SE nor the Biology SE seems to focus on macroscopic modelling, while this SE seems to contain SIR modelling questions. Please let me…

How to define the "R" in SIR model - removed or recovered?
I have been trying to learn more about the SIR model since hearing about it due to recent events. In the process, I have heard various contradictory things. So I am seeking clarity. Specifically, I want to make sure I understand the R in SIR…

Weighing input data in compartmental model fitting
I have a question regarding weighing of data in compartmental modelling.
I have four different compartments between which there are reactions occurring, all of them first order. I have monitored concentrations in these compartments over time, and…

How to estimate SEIR model parameter in R via RSS?
I tried to estimate the SEIR MODEL parameter in R by using the following code .Unfortunately I couldn't get it because I get the following error :
"Error in names(parameters) <- c("beta_value", "gamma_value",
"delta_value") : 'names' [3] has…
