Principal component analysis

Adds output_label to the row attributes.

Parameters:

attributeUnion[str, np.ndarray]

The attribute to be used for PCA. Uses get_attribute() to retrieve the values constrained by row.

componentsint

The number of PCA components to reduce to.

output_labelstr, default PCA_LABEL

The name of the row attribute to store the data in.

show_plotbool

Show the plot for the explained variance by the PCAs.

kwargsdict

Passed to the PCA.
