org.das2.qds.util.LinFit

Linear Fit routine. This will allow errors on the Y values, and will report chi squared. Borrowed from pamguard, https://sourceforge.net/projects/pamguard/.

getA

getA( ) → double

return the result A of the fit y = A + B * x

Returns:

the result A of the fit y = A + B * x
