The log likelihood of a gamma density with data, x, shape, rate
and scale parameters.

likgamma(x, shape, rate = 1, scale = 1/rate, log = TRUE)

## Arguments

x |
vector of quantiles. |

shape |
shape and scale parameters. Must be positive,
`scale` strictly. |

rate |
an alternative way to specify the scale. |

scale |
shape and scale parameters. Must be positive,
`scale` strictly. |

log |
logical; if `TRUE` , probabilities/densities \(p\)
are returned as \(log(p)\). |

## Value

A numeric scalar for the log likelihood of the gamma density given the
data where shape, scale, and rate can be held constant or if vector were given
vector will be returned.

## Details

The log likelihood is the log of a function of parameters given the data.

## Examples

likgamma(x = rgamma(n = 2, shape = 3),
shape = 3)
