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. |
