Linear Regression
qWe have N paired data point (xi, yi) that we want to approximate their relationship with a linear regression:
q              
qThe errors produced by this linear approximation can be estimated as:
q
q           
q
qThe least square linear fit chooses coefficients a and b to produce a minimum value of the error Q.
 a0 = intercept
 a1 = slope (b)
