histogramDS1 {dsBase}R Documentation

returns the minimum and the maximum of the input numeric vector

Description

this function returns the minimum and maximum of the input numeric vector which depends on the argument method.indicator. If the method.indicator is set to 1 (i.e. the 'smallCellsRule' is used) the computed minimum and maximum values are multiplied by a very small random number. If the method.indicator is set to 2 (i.e. the 'deteministic' method is used) the function returns the minimum and maximum values of the vector with the scaled centroids. If the method.indicator is set to 3 (i.e. the 'probabilistic' method is used) the function returns the minimum and maximum values of the generated 'noisy' vector.

Usage

histogramDS1(xvect, method.indicator, k, noise)

Arguments

xvect

the numeric vector for which the histogram is desired.

method.indicator

a number equal to either 1, 2 or 3 indicating the method of disclosure control that is used for the generation of the histogram. If the value is equal to 1 then the 'smallCellsRule' is used. If the value is equal to 2 then the 'deterministic' method is used. If the value is set to 3 then the 'probabilistic' method is used.

k

the number of the nearest neghbours for which their centroid is calculated if the method.indicator is equal to 2 (i.e. deterministic method).

noise

the percentage of the initial variance that is used as the variance of the embedded noise if the method.indicator is equal to 3 (i.e. probabilistic method).

Value

a numeric vector which contains the minimum and the maximum values of the vector
