Hi Guys,
Reviewing the org.apache.commons.math4.fitting.leastsquares.StraightLineProblem
(f(x) = ax + b). For the jacobian we have:
// Partial derivative wrt "a".
jacobian[i][0] = p[0];
// Partial derivative wrt "b".
jacobian[i][1] = 1;
Should it be:
// Partial derivative wrt "a".
jacobian[i][0] = 1;
// Partial derivative wrt "b".
jacobian[i][1] = 0;
Cheers,
Ole
