Prophet: Understanding the parameters in the research paper

[yashkalani]

Hello guys, i've been reading the research paper and under the saturating trend module (logistic growth) as a beginner, i am unable to understand what (m = offset parameter) represents and how (k= base growth rate) is calculated?

The wikipedia article here has a description of the parameters with an illustration: https://en.wikipedia.org/wiki/Logistic_function

The offset parameter m is in wikipedia the x0, the value of the midpoint, where the slope switches from increasing to decreasing.

The growth rate k is in wikipedia also k and determines how steep the curve is.

That is what the parameters mean - how they are actually estimated is just that we find the values that best fit the data. Does that answer your question?
