normal.mle(x)
gumbel.mle(x, tol = 1e-09)
cauchy.mle(x, tol = 1e-09)
logistic.mle(x, tol = 1e-07)
ct.mle(x, tol = 1e-09)
tmle(x, v = 5, tol = 1e-08)
wigner.mle(x, tol = 1e-09)
laplace.mle(x)
``` |

`x` |
A numerical vector with data. |

`v` |
The degrees of freedom of the t distribution. |

`tol` |
The tolerance level up to which the maximisation stops set to 1e-09 by default. |

Instead of maximising the log-likelihood via a numerical optimiser we have used a Newton-Raphson algorithm which is faster. See wikipedia for the equation to be solved. For the t distribution we need the degrees of freedom and estimate the location and scatter parameters.

The Cauchy is the t distribution with 1 degree of freedom. If you want to fit such a distribution used the cauchy.mle and not the t.mle with 1 degree of freedom as it's faster. The Laplace distribution is also called double exponential distribution.

The wigner.mle refers to the wigner semicircle distribution.

Usually a list with three elements, but this is not for all cases.

`iters` |
The number of iterations required for the Newton-Raphson to converge. |

`loglik` |
The value of the maximised log-likelihood. |

`param` |
The vector of the parameters. |
