calculateEllipse: Calculate ellipse 'confidence region'

In GENEAsphere: Visualisation of Raw or Segmented Accelerometer Data

Description

Based on the mean and standard deviation of the elevation and rotation estimates this function will determine the region over which a given proportion of points would be expected to fall.

Usage

calculateEllipse(means, sd, alpha = 0.05)

Arguments

means	A numeric vector of length 2 giving the mean for the x direction and the mean for the y direction.
sd	A numeric vector of length 2 giving the standard deviation for the x direction and the y direction.
alpha	A value between 0 and 1 that gives the confidence level.

Details

Based on the mean and standard deviation of the x and y direction the limits of an ellipse are determined.

Value

A list of length 2 containing:

x	The x axis coordinates of the ellipse
y	The y axis coordinates of the ellipse
