Calibrate the point level totals so their sum matches the regional totals

Calibrate/normalize the point level totals so their sum matches the regional totals. Technically, the totals can be at any level smaller than the region level specified.

Usage

calibrateByRegion(point.totals, point.regions, regions, region.totals)

Arguments

point.totals: Vector of point level totals that will be calibrated/normalized
point.regions: Vector of regions associated with each point
regions: Vector of region names
region.totals: Vector of desired region level totals associated with regions

Value

A vector of same length as point.totals and point.regions containing the calibrated/normalized point totals that sum to the correct regional totals

Vector of updated point level totals, calibrated to match region totals

Examples

point.totals = c(1, 1, 1, 2)
point.regions = c("a", "a", "b", "b")
region.totals = c(10, 20)
regions = c("a", "b")
calibrateByRegion(point.totals, point.regions, regions, region.totals)
