Calculate dynamic body acceleration (DBA) for an acc vector

Source: R/dynamic_acceleration.R
dba.Rd

Compute vectorial dynamic body acceleration (VeDBA) or overall dynamic body acceleration (ODBA) for each burst in an acc vector.

Dynamic body acceleration is computed by subtracting the static acceleration component from each axis and then summarizing the remaining dynamic acceleration with:

  • VeDBA: mean of the Euclidean norm across samples

  • ODBA: mean of the sum of absolute values across samples

Usage

vedba(x)

odba(x)

Arguments

x

An acc vector.

Value

A numeric vector the same length as x.

Examples

a <- acc_example()

vedba(a)
#> [1] 0.6996903 0.5915996
odba(a)
#> [1] 0.8675162 0.8263061
