Parameters to estimate effective reproduction number on your blog

[drkamarul]

Hi Tim,

Your blogs on COVID-19 is very useful and informative. Thank you very much.

When I looked at your parameter on your blog here https://timchurches.github.io/blog/posts/2020-02-18-analysing-covid-19-2019-ncov-outbreak-data-with-r-part-1/#estimating-changes-in-the-effective-reproduction-number, you wrote ... So let’s retain the mean SI estimated by Li et al. of 7.5 days, with an SD of 3.4, but let’s also allow that mean SI to vary between 2.3 and 8.4 using a truncated normal distribution with an SD of 2.0. We’ll also allow the SD or the SD to vary between 0.5 and 4.0.

You could also the image below. My questions are:

• min_mean_si = 1, is it correct?
• std_std_si =1, is it correct?
• where should I put the value of 2.3?

Thanks again.
