Computes deviance and Pearson residuals for eba objects.

1 2	## S3 method for class 'eba' residuals(object, type = c("deviance", "pearson"), ...)

`object`	an object of class `eba`, typically the result of a call to `eba`
`type`	the type of residuals which should be returned; the alternatives are: `"deviance"` (default) and `"pearson"`
`...`	further arguments passed to or from other methods. None are used in this method.

Residuals are computed from the upper triangle of the paired-comparison matrix.

See residuals.glm for details.

A vector of residuals having as many elements as pairs of stimuli.
