In astamm/squad: Statistics for Quaternion Temporal Data

The VESPA64 dataset

Description

A set of QTS representing individual gait patterns (IGPs) of individuals collected under a number of varying factors.

Usage

vespa64

Format

A tibble with 320 rows and 7 columns:

• V: a categorical variable with two levels specifying the ID of the Volunteer;

• E: a categorical variable with two levels specifying the ID of the Experimenter;

• S: a categorical variable with four levels specifying the type of Sensor;

• P: a categorical variable with four levels specifying the Position of the sensor;

• A: a categorical variable with two levels specifying the ID of the Acquisition pathway;

• igp: A 101x5 tibble storing a QTS which represents the IGP of the individual under a specific set of VESPA conditions.

Details

The IGP measures the hip rotation during a typical gait cycle. Each rotation is expressed with respect to the mean position of the sensor during the gait cycle. Each IGP is then straightened so that it is periodic with a last point matching the first one.

It is essentially a reduced version of the VESPA data set where IGPs have been averaged over the repetition for each set of conditions.
