HASPT: Heuristic Algorithms estimating SPT window.

In GGIR: Raw Accelerometer Data Analysis

Heuristic Algorithms estimating SPT window.

Description

As used in function g.sib.det. Function is not intended for direct use by GGIR user.

Usage

HASPT(angle, sptblocksize = 30, spt_max_gap = 60, ws3 = 5, 
      HASPT.algo="HDCZA", HDCZA_threshold = c(), invalid, 
      HASPT.ignore.invalid = FALSE, activity = NULL)

Arguments

angle	Vector of epoch level estimates of angle
sptblocksize	Number to indicate minimum SPT block size (minutes)
spt_max_gap	Number to indicate maximum gap (minutes) in SPT window blocks.
ws3	Number representing epoch length in seconds
HASPT.algo	See GGIR
HDCZA_threshold	See GGIR
invalid	Integer vector with per epoch an indicator of valid(=0) or invalid(=1) epoch.
HASPT.ignore.invalid	Boolean to indicate whether invalid time segments should be ignored
activity	Magnitude of acceleration, only used when HASPT.algo is set to NotWorn. Acceleration metric used is specified by argument acc.metric elsewhere in GGIR.

Value

List with start and end times of the SPT window and the threshold as used.
