# Class "MEDQObj"

### Description

The `MEDQObj`

class holds model specification and output from
the Multivariate Medians and Distance Quantiles procedure. The `summary.MEDQObj`

class
represents the summary of these objects.

### Objects from the Class

Objects can be created by calls of the form `new("MEDQObj", ...)`

or, more commonly, via the
`medq`

function.

### Slots

`NumGrps`

:The number of groups in the input data.

`NumVars`

:The number of response variables used in the multivariate medians and distance quantiles.

`NumObs`

:The total number of observations in the original data set.

`GrpSizes`

:A vector of length

`NumGrps`

specifying group sizes.`inputData`

:A

`data.frame`

used for the analysis.`NumQuantVals`

:The number of quantiles specified in the analysis.

`quant`

:A vector of quantiles used in the analysis.

`MaxGpSize`

:The number of observations in the largest group.

`VariableWInGpMedian`

:Within group median coordinates for specified variables.

`GpAvgDistToGpMVMedian`

:Average distance to multivariate median for each group.

`GpMedQTolerance`

:The solution tolerance.

`WInGpQuantDist`

:Within group distance quantile distance from the median.

`ObsDistToGpMedian`

:The observed distance to the multivariate median.

`NumIterations`

:The number of iterations for convergence to be reached.

`Call`

:The original function call.

`group.names`

:The names of the groups used in the analysis.

### Methods

- Dist2mvm
`signature(x = "MEDQObj")`

: appends the distance to the multivariate median onto the the original input data and returns it.`signature(x = "MEDQObj")`

: same as summary- show
`signature(object = "MEDQObj")`

: same as summary- summary
`signature(object = "MEDQObj")`

: Prints a detailed summary of the MEDQ analysis.
