Detailed Description

Find the minimum, lower quartile, median, upper quartile and maximum of a sample.

Note

D - shared3p protection domain

Supported types - int32 / int64 / float32 / float64

A version of this function which hides the sample size was implemented for the paper "Going Beyond Millionaires: Privacy-Preserving Statistical Analysis" but is not included due to private integer division not working.

Parameters

data	- input sample
isAvailable	- vector indicating which elements of the input sample are available

Returns

returns a vector containing the minimum, lower quartile, median, upper quartile and maximum of the input sample (in that order). If the input size is less than five, a vector of zeroes is returned.

Leakage

Leaks the number of true values in isAvailable
