In bogdanoancea/deduplication: R package for computing the duplicity probility for each mobile device.

Description

Computes the center of probabilities (as center of mass) for each posterior probability cloud, at each time instant, for a device. It uses the results obtained from destim package.

Usage

centerOfProbabilities(centroid, postLocProb)

Arguments

centroid	A data.table object with the centroids for each tile in the grid.
postLocProb	a Matrix object with the posterior location probabilities computed by destim for a device. The number of rows equals the number of tiles and the number of columns equals the number of successive time instants. An element postLocProb[i,j] represents the posterior location probability corresponding to tile i at the time instant j.

Value

A table with two columns: centerProb_x and centerProb_y representing the x and y coordinates of the centers of probabilities.
