Linear Regression Create a set of points like this (all on one line): p = [[0, 3.8414709848078967], [0.6931471805599453, 6.6818861490654635], [1.0986122886681098, 7.5355691627323065], [1.3862943611198906, 7.788374949171635], [1.6094379124341003, 8.478827375073264], [1.791759469228055, 9.887622378713294], [1.9459101490553132, 11.440627194940042], [2.0794415416798357, 12.307124413342725]] Where: p[i][0] is an x value and p[i][1] is the corresponding y value Find the least square curve that best matches these points using linear regression.

          Linear Regression

Create a set of points like this (all on one line):
p =
[[0, 3.8414709848078967], [0.6931471805599453, 6.6818861490654635], [1.0986122886681098, 7.5355691627323065], [1.3862943611198906, 7.788374949171635], [1.6094379124341003, 8.478827375073264], [1.791759469228055, 9.887622378713294], [1.9459101490553132, 11.440627194940042], [2.0794415416798357, 12.307124413342725]]

Where:
p[i][0] is an x value
and p[i][1] is the corresponding y value

Find the least square curve that best matches these points using linear regression.

I need four outputs:
n = number of points
m = slope
b = y-intercept
r = coefficient of regression.

Formulas that might help:
n = p.length
m = (n * Î£xy - Î£x * Î£y) / (n * Î£xx - Î£x * Î£x)
b = (Î£y - m * Î£x) / n
r = (n * Î£xy - Î£x * Î£y) / sqrt((n * Î£xx - Î£x * Î£x) * (n * Î£yy - Î£y * Î£y))
