QUESTION

I was wondering if anyone could help me with this problem that has been plaguing me.

The error occurs next to the line in my code that says "#include

I have ran the following code as well and it did not change the outcome

QUESTION

I have an array of values (concentration values), with each value taken at a different time point. I need to fit a gamma-variate curve (formula is in the picture below) to these values (i.e. find alpha and beta such that the curve best fits those points - all other variables are known.)

an example of the values i might get (crosses), and the curve I'd want to fit:

I have no idea how to do this. I tried to fit a simplified version of the formula, one that can be solved by using linear regression, by using matrices but I couldn't get it to work. That version of the formula (in which you only solve for one variable, alpha) looks like this:

simplified version, which would also be fine:

my attempt to solve fit the linear regression curve using matrices, using the vnl library (https://vxl.github.io/doc/release/core/vnl/html/index.html) looked like this. I was following this guy's tutorial (https://machinelearningmastery.com/solve-linear-regression-using-linear-algebra/)

Maybe try NLOpt? Here is an example of how to use it. Also, you could look at this code which fits a polynomial to points in 3D space.
