NormalVaRPlot2DCL {Dowd} | R Documentation |

## Plots normal VaR against confidence level

### Description

Plots the VaR of a portfolio against confidence level assuming that P/L are normally distributed, for specified confidence level and holding period.

### Usage

```
NormalVaRPlot2DCL(...)
```

### Arguments

`...` |
The input arguments contain either return data or else mean and standard deviation data. Accordingly, number of input arguments is either 3 or 4. In case there are 3 input arguments, the mean and standard deviation of data is computed from return data. See examples for details. returns Vector of daily geometric return data mu Mean of daily geometric return data sigma Standard deviation of daily geometric return data cl VaR confidence level and must be a vector hp VaR holding period and must be a scalar |

### Examples

```
# Plots VaR against confidene level given P/L data
data <- runif(5, min = 0, max = .2)
NormalVaRPlot2DCL(returns = data, cl = seq(.85,.99,.01), hp = 60)
# Computes VaR against confidence level given mean and standard deviation of return data
NormalVaRPlot2DCL(mu = .012, sigma = .03, cl = seq(.85,.99,.01), hp = 40)
```
