[Math]Higher precision for Significance using Math Component

["Dahake, Nikhil" <nd...@uncc.edu>]

Hi,

I am using the SimpleRegression class's getSignificance() method to calculate the Significance on certain data. The lowest non zero value that this method currently returns is : 2.220446e-16 (for the data that I am analyzing).

However, I need a higher precision. For example, on analysis with an another library the lowest non zero value I got was : 9.262178e-98

How can I get a very high precision with regards to significance using the SimpleRegression class? Please let me know.

Thank you,
Nikhil Dahake

How does significance make any sense at all at these levels?  How can
higher precision do you any good at all?  Can't you just use the underlying
z-score (or whatever) directly instead of precision?
