PDL1RP {mcradds}

PD-L1 Reader Precision Data

Description

This dummy data set is from a PD-L1 HE stained study to estimate the reproducibility of one assay in determining the PD-L1 status of NSCLC tissue specimens. It contains three sub-data to compute the reproducibility within reader (one pathologists, also called reader here, scores one specimen three times), between reader (three readers scores the same specimen) and between site (one reader in three sites scores the same specimens). These data sets don't have the reference for the each score so it can be only used in the pairwise comparison to calculate the APA, ANA and OPA which don't reply on the reference.
