scan_pb_perm_cpp: Calculate the space-time permutation scan statistic.

In BenjaK/scanstatistics: Space-Time Anomaly Detection using Scan Statistics

Description

Calculate the space-time permutation scan statistic (Kulldorff 2005) and Monte Carloo replicates.

Usage

scan_pb_perm_cpp(counts, baselines, zones, zone_lengths, store_everything,
  num_mcsim)

Arguments

counts	An integer matrix (most recent timepoint in first row).
baselines	A matrix with positive entries (most recent timepoint in first row).
zones	An integer vector (all zones concatenated; locations indexed from 0 and up)
zone_lengths	An integer vector.
store_everything	A boolean.
num_mcsim	An integer.

Value

A list with elements observed and simulated, each being a data frame with columns:

zone

The top-scoring zone (spatial component of MLC).

duration

The corresponding duration (time-length of MLC).

score

The value of the loglihood ratio statistic (the scan statistic).

relrisk_in

The estimated relative risk inside.

relrisk_in

The estimated relative risk outside.
