Arguments
| :: Vector Double | x data |
| -> Vector Double | y data |
| -> (Double, Double, Double, Double, Double, Double) | (c_0,c_1,cov_00,cov_01,cov_11,chi_sq) |
fits the model Y = C X
Arguments
| :: Vector Double | x data |
| -> Vector Double | x weights |
| -> Vector Double | y data |
| -> (Double, Double, Double, Double, Double, Double) | (c_0,c_1,cov_00,cov_01,cov_11,chi_sq) |
fits the model Y = C X, with x data weighted
Arguments
| :: Double | x data point |
| -> Double | c0 |
| -> Double | c1 |
| -> Double | cov00 |
| -> Double | cov01 |
| -> Double | cov11 |
| -> (Double, Double) | (y,error) |
computes the fitted function and standard deviation at the input point
Arguments
| :: Matrix Double | design matrix (X) |
| -> Vector Double | observations |
| -> (Vector Double, Matrix Double, Double) | (coefficients,covariance,chi_sq) |
fit the model Y = C X, with design matrix X | X is a design matrix X_{ij} = x_j(i) with i observations and p predictors | a polynomial would be X_{ij} = x_i^j | a fourier series would be X_{ij} = sin (omega_j x_i)
