st: Stata command for parameter calculation with least square method?
for given data points I want to find out a parameter for a function such
that the function fits best to the data points.
The function would be: f(x)=x^alpha.
The data points are:
I know how I could do that with the least square method and the Excel
Which Stata command would deliver the same result? Is _reg3_ the appropriate
command? How would the command line look like?
Furthermore, I want to do the same with 2 unknown parameters, e.g. for the
function f(x)=-k*(-x)^alpha. Which command would be appropriate for 2
unknown parameters (here: k and alpha)?
Any comments would be greatly appreciated.
