get_2d_confidence_ellipse(→ numpy.ndarray)

Generates points for plotting a 2-d ellipse containing conf% of probability mass for a Normal distribution.

janelia_core.stats.utils.get_2d_confidence_ellipse(mn: numpy.ndarray, cov: numpy.ndarray, conf: float, n_side_pts: int = 100) → numpy.ndarray

Generates points for plotting a 2-d ellipse containing conf% of probability mass for a Normal distribution.

Args:

mn: The mean for the distribution.

cov: The covariance matrix for the distribution.

conf: The confidence to produce the ellipse for

n_side_pts: The number of points to generate for each half of the ellipse. Must be even.

Returns:

pts: The points defining the ellipse. Each row is a point. There will 2*n_side_pts total points returned.

Raises:

ValueError: If inputs are not the right shape
