bootSummary function

Compute usual summary stats of 'sum' indexes from bootPairs output

Begin with the output of bootPairs function, a (n999 by p-1) matrix when there are p columns of data, bootSummary produces a (6 by p-1) mtx of summary of bootstrap ouput (Min, 1st Qu,Median, Mean, 3rd Qi.,Max)

bootSummary(out, per100 = TRUE)

Arguments

• out: output from bootPairs with p-1 columns and n999 rows in input here
• per100: logical (default per100=TRUE) to change the range of 'sum' to [-100, 100] values which are easier to interpret

Returns

summ summary output from the (n999 by p-1) matrix output of bootPairs(mtx)

each containing resampled sum' values summarizing the weighted sums associated with all three criteria from the function silentPairs(mtx)`

applied to each bootstrap sample separately.

Examples

## Not run:

options(np.messages = FALSE)
set.seed(34);x=sample(1:10);y=sample(2:11)
bb=bootPairs(cbind(x,y),n999=29)
bootSummary(bb) #gives summary stats for n999 bootstrap sum computations

bb=bootPairs(airquality,n999=999);options(np.messages=FALSE)
bootSummary(bb)#signs for n999 bootstrap sum computations

data('EuroCrime')
attach(EuroCrime)
bb=bootPairs(cbind(crim,off),n999=29) #col.1= crim causes off 
#hence positive signs are more intuitively meaningful.
#note that n999=29 is too small for real problems, chosen for quickness here.
bootSummary(bb)#signs for n999 bootstrap sum computations
## End(Not run)
