## The Exponentially Modified Gaussian Distribution

### Description

Density, distribution function, and random generation
for the exponentially modified Gaussian distribution with
mean `mu`

and standard deviation `sigma`

of the gaussian
component, as well as scale `beta`

of the exponential
component.

### Usage

```
dexgaussian(x, mu, sigma, beta, log = FALSE)
pexgaussian(q, mu, sigma, beta, lower.tail = TRUE, log.p = FALSE)
rexgaussian(n, mu, sigma, beta)
```

### Arguments

`x` , `q` |
Vector of quantiles. |

`mu` |
Vector of means of the combined distribution. |

`sigma` |
Vector of standard deviations of the gaussian component. |

`beta` |
Vector of scales of the exponential component. |

`log` |
Logical; If |

`lower.tail` |
Logical; If |

`log.p` |
Logical; If |

`n` |
Number of draws to sample from the distribution. |
