1. A method of point cloud coding, executable by a processor, comprising:
receiving, from a bitstream, data corresponding to a point cloud;
obtaining from the data a first prediction residual of a first component from among a plurality of components of an attribute associated with the point cloud;
reconstructing the first prediction residual;
determining a predicted second prediction residual based on the reconstructed first prediction residual and at least one model parameter;
obtaining a second prediction residual of a second component from among the plurality of components based on the predicted second prediction residual;
reconstructing the second prediction residual; and
decoding the data corresponding to the point cloud based on the reconstructed first prediction residual and the reconstructed second prediction residual.
