WLS

Struct WLS

pub struct WLS;

Expand description

Weighted Least Squares estimator.

Transforms the model by sqrt(w): y* = sqrt(w)y, X = sqrt(w)*X, then runs OLS on the transformed data.

Implementations§

impl WLS

pub fn from_formula( formula: &Formula, data: &DataFrame, weights: &ArrayBase<OwnedRepr<f64>, Dim<[usize; 1]>>, cov_type: CovarianceType, ) -> Result<OlsResult, GreenersError>

Fit WLS from a formula, DataFrame, and weight column name.

pub fn fit( y: &ArrayBase<OwnedRepr<f64>, Dim<[usize; 1]>>, x: &ArrayBase<OwnedRepr<f64>, Dim<[usize; 2]>>, weights: &ArrayBase<OwnedRepr<f64>, Dim<[usize; 1]>>, cov_type: CovarianceType, ) -> Result<OlsResult, GreenersError>

Fit WLS from arrays.

pub fn fit_with_names( y: &ArrayBase<OwnedRepr<f64>, Dim<[usize; 1]>>, x: &ArrayBase<OwnedRepr<f64>, Dim<[usize; 2]>>, weights: &ArrayBase<OwnedRepr<f64>, Dim<[usize; 1]>>, cov_type: CovarianceType, variable_names: Option<Vec<String>>, ) -> Result<OlsResult, GreenersError>

Fit WLS with variable names.
