Partial Least Squares cross-decomposition (PLS regression)¶
Finds the fundamental relations between two matrices X and Y, ie. it finds the (multidimensional) direction in X that best explains maximum multidimensional direction in Y. See also PCA-analysis
Configuration:
n_components
Number of components to keep.
scale
whether to scale the data
max_iter
the maximum number of iterations of the NIPALS inner loop (used only if algorithm=”nipals”)
tol
Tolerance used in the iterative algorithm default 1e-06.
Attributes:
x_weights_
X block weights vectors.
y_weights_
Y block weights vectors.
x_loadings_
X block loadings vectors.
y_loadings_
Y block loadings vectors.
x_scores_
X scores.
y_scores_
Y scores.
x_rotations_
X block to latents rotations.
y_rotations_
Y block to latents rotations.
coef_
The coefficients of the linear model:
Y = X coef_ + Err
n_iter_
Number of iterations of the NIPALS inner loop for each component.
