dwdcomppareto {CompPareto} | R Documentation |

## The probability mass function (pmf) of a discrete composite distribution with Pareto tail

### Description

`dwdcomppareto`

returns the pmf of a discrete composite distribution with a Pareto upper tail at a point x, with a specified distribution at the lower tail.

### Usage

```
dwdcomppareto(x, spec, alpha, theta, log = FALSE, ...)
```

### Arguments

`x` |
A scalar or vector of nonnegative integer values at which the probability mass needs to be evaluated |

`spec` |
The selection of the lower tail (head) distribution |

`alpha` |
The shape parameter of the Pareto distribution |

`theta` |
The scale parameter of Pareto, also serve as the location parameter of the composite model |

`log` |
logical; if TRUE, probability p are given as log(p) |

`...` |
The parameter of the lower tail (head) distribution |

### Value

an object of the same length of x as the probability mass evaluated at x

### Examples

```
x<-1:100
dwdcomppareto(x, "lnorm", 0.4, 1, meanlog = 1, sdlog = 0.8)
dwdcomppareto(x, "weibull", alpha = 1.5, theta = 1.5, shape = 2, scale = 2)
```
