## Symmetric simultaneous bayesian confidence bands

### Description

`simcnfB`

obtains symmetric bayesian distribution confidence bands

### Usage

```
simcnfB(DF, DFmat, alpha = 0.05, scale = FALSE)
```

### Arguments

`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 |

### Value

cstar - a constant to add and subtract from DF to create confidence bands if no scaling=FALSE else a vector of length DF.

### Examples

```
set.seed(14); m=matrix(rbeta(500,1,4),nrow = 5) + 1:5
DF = apply(m,1,mean); plot(1:5,DF,type="l",ylim = c(0,max(m)), xlab = "Index")
symCB<- simcnfB(DF,DFmat = m)
lines(1:5,DF-symCB,lty=2); lines(1:5,DF+symCB,lty=2)
```
