Auto Select methodMethod-1 : `byx = (n amount xy - (sum x)(amount y))/(n sum x^2 - (amount x)^2), bxy = (n amount xy - (sum x)(sum y))/(n amount y^2 - (sum y)^2)`Method-2 : `byx = (sum (x - bar x)(y - bar y))/(sum (x - bar x)^2), bxy = (sum (x - bar x)(y - bar y))/(sum (y - bar y)^2)`Or `byx = (n amount dx dy - (amount dx)(amount dy))/(n amount dx^2 - (sum dx)^2), bxy = (n amount dx dy - (amount dx)(amount dy))/(n amount dy^2 - (sum dy)^2)`
