Statistics: ricelike

### Function Reference: `ricelike`

statistics: nlogL = ricelike (params, x)
statistics: [nlogL, acov] = ricelike (params, x)
statistics: […] = ricelike (params, x, censor)
statistics: […] = ricelike (params, x, censor, freq)

Negative log-likelihood for the Rician distribution.

`nlogL = ricelike (params, x)` returns the negative log likelihood of the data in x corresponding to the Rician distribution with (1) non-centrality (distance) parameter nu and (2) scale parameter sigma given in the two-element vector params.

`[nlogL, acov] = ricelike (params, x)` also returns the inverse of Fisher’s information matrix, acov. If the input parameter values in params are the maximum likelihood estimates, the diagonal elements of params are their asymptotic variances.

`[…] = ricelike (params, x, censor)` accepts a boolean vector, censor, of the same size as x with `1`s for observations that are right-censored and `0`s for observations that are observed exactly. By default, or if left empty, `censor = zeros (size (x))`.

`[…] = ricelike (params, x, censor, freq)` accepts a frequency vector, freq, of the same size as x. freq typically contains integer frequencies for the corresponding elements in x, but it can contain any non-integer non-negative values. By default, or if left empty, `freq = ones (size (x))`.
