About this predictor:
PCLR is a method of predicting chloroplast localization of proteins in plant cells. The prediction algorithm was trained using principal component logistic regression with stepwise variable selection. The actual principal components and their weights are shown here.
PCLR is described in: Andrew I. Schein, Jessica C. Kissinger, and Lyle H. Ungar. Chloroplast Transit Peptide Prediction: a Peek Behind the Black Box. Nucleic Acids Research, 2001, Vol 29, No. 16 e82.
