## MLE of the ordinal model without covariates

### Description

MLE of the ordinal model without covariates.

### Usage

    ordinal.mle(y, link = "logit")

### Arguments

`y` | A numerical vector with values 1, 2, 3,..., not zeros, or an ordered factor.
`link` | This can either be "logit" or "probit". It is the link function to be used.

### Details

Maximum likelihood of the ordinal model (proportional odds) is implemented. See for example the "polr" command in R or the examples.

### Value

A list including:

`loglik` | The log-likelihood of the model.
`a` | The intercepts (threshold coefficients) of the model.
