Calculates Pearson's product-moment correlation between two containers, x and y.
![\[r_{1,2}=\frac{y_1\times y_2}{\sqrt{\sum_{i=1}^{i=n} y_1^2 \times \sum \sum_{i=1}^{i=n} y_2^2}}\]](form_37.png)
From Sokal and Rohlf. Biometry, 3rd ed. 1995, Freeman Press, page 571.
- Parameters:
-
beg_x pointer to beginning of xend_x pointer to one past the end of xbeg_y pointer to beginning of y
- Note:
- the square of the return value is the well-know coefficient of determination, r^2

template<typename iterator >
| double Sequence::variance | ( | iterator | beg, | |
| iterator | end | |||
| ) | [inline] |
- Parameters:
-
beg an iterator end an iterator
- Returns:
- the variance of the range
- Examples:
- critical_values.cc.
