I am trying to optimise k_parameter, sdr_max, and ic0
I have batch run the sdr model for a given area, iterating over every combination of
sdr_max for 0 < sdrmax < 4
k_parameter for 1 < k_parameter < 4
ic0 for 0 < ico < 2
8000 iterations in total, and I plotted the result of sum of all non-NA values of sed_deposition.tif
Another modeler has estimated the same land area as having ~6400 tons of sediment
The 3d scatterplot shows us all of the models whose sum(sed_deposition) < 9000 tons. You can see there are several model runs that fall in a similar area, some with sdr_max = 3,1.5-2, 0.5, etc. with k_param around 4, and 0.5 < ic0< 2.
I have 2 questions:
Are these all valid parameter space values? Or or are the parameters (k_param, ic0, sdr_max) constrained over some range? (e.g., 0-1)
And: using outputs from various iterations, can I add an error estimate or confidence interval to the model?
I hope to find optimal parameters
I have an excellent graph
