lightkurve.correctors.DesignMatrix.pca#
- DesignMatrix.pca(nterms=6, n_iter=10)[source]#
Returns a new
DesignMatrixwith a smaller number of regressors.This method will use Principal Components Analysis (PCA) to reduce the number of columns in the matrix.
- Parameters
- ntermsint
Number of columns in the new matrix.
- n_iterint
Number of iterations that will be run by the power iteration algorithm to compute the principal components.
- Returns
DesignMatrixA new design matrix with PCA applied.
