sales_dataset_test: Sales time-series test

In SeqDetect: Sequence and Latent Process Detector

Description

Sales dataset taken from [2], which comprises 811 product one year sales quantities. We applied this dataset to test the Sequence Detector. The results are available in [1]. The results of the test are various statistics on detected sequences. The testing set of products is re-tested by simultaneously rising the projection threshold, until no more sequences could be detected or max_th parameter is reached.

Usage

sales_dataset_test(learning_set = 1:20, testing_set = 21:40,
  th_increment = 1, max_th = NULL)

Arguments

learning_set	(vector) - A set of products to learn ETTs in the Sequence Detector.
testing_set	(vector) - A set of products to test previously learned sales numbers.
th_increment	(integer) - A threshold increment between two tests.
max_th	(integer) - Maximal thershold for testing. When reached, no further tests and no further threshold increment is done. If NULL, re-testing is done while there are some sequences detected.

Value

A list that comprises sequence statistics for all tests and thresholds.
