Lau and Green posterior loss function
green_loss(object, truth = NULL, tau = 0.5, a = 1, b = 1) # S3 method for default green_loss(object, truth = NULL, tau = 0.5, a = 1, b = 1)
| object | an object with N X N cluster pairwise probability matrix and N X K cluster matrix list entries |
|---|---|
| truth | True adjacency matrix |
| tau | loss function tuning parameter |
| a | misclassification penalty parameter |
| b | misclassification penalty parameter - see Green and Lau for details |
list of three objects (1)loss: the loss corresponding to each clustering configuration, (2) best_loss_ix: The index corresponding to the "best" partition, and (3) mode: the best partition itself
default: classification loss function
