`R/Chi-Squared.R`

The log likelihood of a chi-squared density with data, x, df and ncp parameters.

likchisq(x, df, ncp = 0, log = TRUE)

x | vector of quantiles. |
---|---|

df | degrees of freedom (non-negative, but can be non-integer). |

ncp | non-centrality parameter (non-negative). |

log | logical; if TRUE, probabilities p are given as log(p). |

A numeric scalar for the log likelihood of the chi-squared density given the data where df and ncp can be held constant or if vector were given vector will be returned.

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