Summary statistics for paired samples

Description

Classical and robust statistics (location, scale and correlation) for paired samples.

Usage

## S4 method for signature 'paired'
summary(object,tr=0.2)

Arguments

`object`	an object of class paired.
`tr`	percenatge of trimming.

Value

A list with a first table corresponding to location and scale statistics and a second table to Pearson and winsorized correlation.

The first table contains four rows corresponding to calculations for x, y, x-y and (x+y)/2 variables. The location and scale statistics are given in columns.

`n`	sample size.
`mean`	mean.
`median`	median.
`trim`	trimmed mean (tr=0.2)
`sd`	standard deviation.
`IQR`	interquartile range (standardised to be consistent with the sd in the normal case)
`median ad`	median of absolute deviations (standardised)
`mean ad`	mean of absolute deviations (standardised)
`sd(w)`	winsorised standard deviation (tr=0.2 and standardised)
`min`	minimum value.
`max`	maximum value.
