NettetThe least squares approximation needs a small modification, resulting in the weighted least squares (WLS) approximation. You should try to derive the formula by yourself. Let’s use weights of 0.25 for the snow affected Lapland region, 0.5 for the slightly erroneous measurements, and stick to 1 for the others.

NettetHere's a super simple example. Picture a paraboloid, so like a bowl with sides growing like a parabola. If we put the bottom at coordinates (x, y) = (a, b) and then minimize the height of the paraboloid over all values of x and y - we would expect the minimum to be x=a and y=b. Here's code that would do this. NettetA parameter determining the initial step bound (factor * diag * x ). Should be in interval (0.1, 100). diag sequence, optional.

The indexing is from the least significant bit. For example: bin (136) '0b10001000'. If x=88 the output should be 5. To make this work properly we also need a test that the number of bits set is at least 2. Luckily bin (x).count ('1') will do that.
