/**
|
||||
* Solves a linear least squares problem to obtain a N degree polynomial that fits
|
||||
* the specified input data as nearly as possible.
|
||||
*
|
||||
* Returns true if a solution is found, false otherwise.
|
||||
*
|
||||
* The input consists of two vectors of data points X and Y with indices 0..m-1
|
||||
* along with a weight vector W of the same size.
|
||||
*
|
||||
* The output is a vector B with indices 0..n that describes a polynomial
|
||||
* that fits the data, such the sum of W[i] * W[i] * abs(Y[i] - (B[0] + B[1] X[i]
|
||||
* + B[2] X[i]^2 ... B[n] X[i]^n)) for all i between 0 and m-1 is minimized.
|
||||
*
|
||||
* Accordingly, the weight vector W should be initialized by the caller with the
|
||||
* reciprocal square root of the variance of the error in each input data point.
|
||||
* In other words, an ideal choice for W would be W[i] = 1 / var(Y[i]) = 1 / stddev(Y[i]).
|
||||
* The weights express the relative importance of each data point. If the weights are
|
||||
* all 1, then the data points are considered to be of equal importance when fitting
|
||||
* the polynomial. It is a good idea to choose weights that diminish the importance
|
||||
* of data points that may have higher than usual error margins.
|
||||
*
|
||||
* Errors among data points are assumed to be independent. W is represented here
|
||||
* as a vector although in the literature it is typically taken to be a diagonal matrix.
|
||||
*
|
||||
* That is to say, the function that generated the input data can be approximated
|
||||
* by y(x) ~= B[0] + B[1] x + B[2] x^2 + ... + B[n] x^n.
|
||||
*
|
||||
* The coefficient of determination (R^2) is also returned to describe the goodness
|
||||
* of fit of the model for the given data. It is a value between 0 and 1, where 1
|
||||
* indicates perfect correspondence.
|
||||
*
|
||||
* This function first expands the X vector to a m by n matrix A such that
|
||||
* A[i][0] = 1, A[i][1] = X[i], A[i][2] = X[i]^2, ..., A[i][n] = X[i]^n, then
|
||||
* multiplies it by w[i]./
|
||||
*
|
||||
* Then it calculates the QR decomposition of A yielding an m by m orthonormal matrix Q
|
||||
* and an m by n upper triangular matrix R. Because R is upper triangular (lower
|
||||
* part is all zeroes), we can simplify the decomposition into an m by n matrix
|
||||
* Q1 and a n by n matrix R1 such that A = Q1 R1.
|
||||
*
|
||||
* Finally we solve the system of linear equations given by R1 B = (Qtranspose W Y)
|
||||
* to find B.
|
||||
*
|
||||
* For efficiency, we lay out A and Q column-wise in memory because we frequently
|
||||
* operate on the column vectors. Conversely, we lay out R row-wise.
