Return the parameters and error for a least squares line fit of one segment of a sequence

Return a list of line segments that approximate the sequence. The list is computed using the bottom-up technique. Parameters

Return (x0,y0,x1,y1) of a line fit to a segment using a simple interpolation

Return (x0,y0,x1,y1) of a line fit to a segment of a sequence using linear regression

Return a list of line segments that approximate the sequence. The list is computed using the sliding window technique. Parameters

Return the sum of squared errors for a least squares line fit of one segment of a sequence

Return a list of line segments that approximate the sequence. The list is computed using the bottom-up technique. Parameters
