Calculation of alpha

Function to find the largest alpha that makes equation 10 in the paper solvable.

Usage

FindAlpha(a, b, tryViaQR = TRUE)

FindAlphaSimple(a, b)

Arguments

a

matrix E in paper

b

matrix Eg in paper

tryViaQR

When TRUE QR transformation used (to handle collinearity) when ordinary calculations fail.

Value

alpha

Note

FindAlphaSimple performs the calculations by a simple/direct method. FindAlpha is made to handle problematic special cases.
