Detailed Description

Class Stat2_: Two-variable simple statistics class.

A Stat2_ object contains two Stat_ objects (Xs and Ys) plus a mixed-sum member Sxy for correlation. Data point addition is done by pairs. The one-var stats (min/max/avg, SD) are done via returning Xs or Ys and then using the appropriate Stat_ methods.

clear(): clear the calling object. Definition at line 162 of file Stat2.hh.

void RazorBack::Stat2_::add ( double X, double Y ) [inline]

add(): adds a pair of values X,Y to the calling object. Definition at line 165 of file Stat2.hh.

unsigned int RazorBack::Stat2_::data_no ( ) const [inline]

Returns the number of data pairs seen. Definition at line 168 of file Stat2.hh.

const Stat_ & RazorBack::Stat2_::xs ( ) const [inline]

xs(), ys(): return the one-stat objects for X and Y. Use the Stat_ methods on these to obtain avg, sd, min, max. Definition at line 174 of file Stat2.hh.

const Stat_ & RazorBack::Stat2_::ys ( ) const [inline]

Definition at line 175 of file Stat2.hh.

double RazorBack::Stat2_::corr ( ) const

corr(): returns the correlation coefficient between the X and Y points. Throws Statexc_ if there were no data points. Throws Sdevexc_ if the s.d. was not larger than 0.0.
