asymcnfB
obtains asymmetric bayesian distribution confidence bands
asymcnfB(DF, DFmat, alpha = 0.05, scale = FALSE)
DF |
the target distribution/quantile function as a vector |
DFmat |
the matrix of draws of the distribution, rows correspond to
elements in |
alpha |
level such that |
scale |
logical for scaling using the inter-quartile range |
cstar - a constant to add and subtract from DF to create confidence bands if no scaling=FALSE else a vector of length DF.
