summary.reStruct-class {lme4} | R Documentation

## Class "summary.reStruct"

### Description

A summary of an `reStruct` object. The summary contains information derived from the original object.

### Objects from the Class

Objects from the class are usually constructed by the `summary` generic function applied to an `reStruct` object.

### Slots

`fixed`:
  `"formula"`: the formula defining the fixed-effects.
`coefficients`:
  A matrix containing the fixed-effects coefficients, their standard errors and the t statistics.
`scale`:
  `"numeric"`. The estimate of the scale parameter in the distribution of the per-observation random variation, if it is estimated. In the case of a `"lme"` model this is the estimated standard deviation of the lowest level noise term in the model.
`denomDF`:
  `"integer"`: vector of denominator degrees of freedom.
`REML`:
  `"logical"`: was the REML criterion used to estimate the parameters?
`random`:
  `"lmeLevelList"`: as in the `reStruct` object from which this was derived.
`ngrps`:
  `"integer"`: number of groups at each level of random effects.
`nobs`:
  `"integer"`: total number of observations.
`corFixed`:
  `"corrmatrix"`: Correlation of the estimates of the fixed-effects parameters.
`reSumry`:
  `"list"`: a summary of the random effects parameter estimates
`useScale`:
  `"logical"`: should the `"scale"` slot be used when calculating the variances and covariances of the random effects?
`showCorrelation`:
  `"logical"`: should the `"corFixed"` slot be shown in the summary.

### Methods
