How to estimate the initial values of parameters in Interferometric water cloud model in R?

03 April 2019 1 897 Report

In interferometric water cloud model we estimate 3 unknown parameters via non-linear least square regression, but if we do not mention proper initial values of those parameters, regression process doesn't complete. I am trying to find how to assign the initial parameters in a correct way.

Wietske Bijker

The water cloud model has been around for some time, so you could find from literature a few examples of values for the three parameters, preferably from similar land cover or objects to what you are studying. The more realistic the initial values, the faster the process will converge to a solution.
