Linear regression The Linear regression formula is in relation to two variables:
y =  A + Bx
  Example: By the following investment and yield table, calculate the 
linear regression (regression coe fficient  A, regression coe fficient B) of 
capital investment verse yield, the correlation coe fficient, the minimum 
value of investment, the maximum value of yield (%), and the yield 
percentage at 45 thousand unit of investment, and the investment unit 
at 180% yield.
