Description

Plot the Network information criterion (NIC), effective number of parameters (ENP), and estimated proportion (pi0) of true null hypotheses for different choices of tuning parameters; also plot the estimated density of noncentrality parameters

## S3 method for class 'nparncpt'
plot(x, ...)

Arguments

x

an object of class nparncpt

Details

For NIC, only values within 2 s.e.'s of the minimum are shown. The solid line on NIC, ENP and pi0 shows the final tuning parameter, i.e., the one that minimizes NIC.
