regress(x, y, len ) regress: computes alpha, beta, and r^2 for a linear regression of y on x
    x: the explaining (independent) variable
    y: the dependent variable
    len: use the most recent "len" values of x and y
  Returns: : alpha is the x-intercept, beta is the slope, an r2 is the coefficient of determination
