In IQSS/PSI-Library: Differentially Private Statistical Releases for Privacy Preservation

Description

Note that covariance matrices are symmetric and thus only the lower triangle needs to be calculated, so this is equivalent to the number of values that will need to be differentially privately calculated.

Usage

lowerTriangleSize(columns)

Arguments

columns

Vector of column names, indicating columns of a data frame that the covariance matrix will be calculated over.

Details

If the user input output covariance matrix will have dimension lower triangle of the matrix will have size

Value

Integer. Size of lower triangle of the covariance matrix that will be generated by covariance statistic. INCLUDING DIAGONAL
