The log likelihood of a F density with data, x, df1, df2 and ncp parameters.

likf(x, df1, df2, ncp, log = TRUE)

Arguments

x

vector of quantiles.

df1

degrees of freedom. Inf is allowed.

df2

degrees of freedom. Inf is allowed.

ncp

non-centrality parameter. If omitted the central F is assumed.

log

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

Value

A numeric scalar for the log likelihood of the f density given the data where df1, df2, and ncp 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

likf(x = rf(n = 2, df1 = 3, df2 = 4), df1 = 3, df2 = 4)
