Syntax
[q, info] = nrregr2(func, p, x, y, Z, W)
Description
Calculates least squares estimates using Newton Raphson method for bivariate data
Input
- func: string with name of user-defined function
f = func (p, x, y) with p: np-vector; x: nx-vector; y: ny-vector f: (nx,ny)-matrix with model-predictions for dependent variable
- p: (np,2) matrix with
p(:,1) initial guesses for parameter values p(:,2) binaries with yes or no iteration (optional)
- x: (nx,1)-vector with first independent variable
- y: (ny,1)-vector with second independent variable
- Z: (nx,ny)-matrix with dependent variable
- W: (nx,ny)-matrix with weight coefficients (optional)
Output
- q: matrix like p, but with least squares estimates
- info: 1 if convergence has been successful; 0 otherwise
Remarks
Calls nrdregr2, and user-defined function 'func'. Set options with nrregr_options
