tVaRPlot2DCL {Dowd} | R Documentation |

## Plots t VaR against confidence level

### Description

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

### Usage

```
tVaRPlot2DCL(...)
```

### Arguments

`...` |
The input arguments contain either return data or else mean and standard deviation data. Accordingly, number of input arguments is either 4 or 5. In case there 4 input arguments, the mean and standard deviation of data is computed from return data. See examples for details. returns Vector of daily P/L data data mu Mean of daily P/L data data sigma Standard deviation of daily P/L data data df Number of degrees of freedom in the t distribution 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
data <- runif(5, min = 0, max = .2)
tVaRPlot2DCL(returns = data, df = 6, cl = seq(.85,.99,.01), hp = 60)
# Computes VaR against confidence level given mean and standard deviation of P/L data
tVaRPlot2DCL(mu = .012, sigma = .03, df = 6, cl = seq(.85,.99,.01), hp = 40)
```
