gives the coefficients in the equation of the regression line and this is the routine that is built into all calculators and software packages that produce the regression line for any set of data. We next investigate the conditions under which the solutions for a and b are not defined. For simplicity, consider n = 3 points at x = x1, x2, and x3.

Did the student find the extrema (vertex at x=-b/(2a))for the quadratic regression? Did the student find the exponential regression’s rate of growth or decay. (Find ln(b) and write as percent) Which is it? Growth(b is positive) or Decay(b is negative) Where is the asymptote for the exponential regression? (calculator uses only y=0, but you ...

Use your calculator to determine the regression line for predicting an animal’s longevity from its gestation period. Write the regression equation below. (Note: On your calculator, enter LinReg LGEST, LLONG, Y2. This will store the regression equation in Y2.) What longevity does this line predict for an animal with a gestation period of 365 days?

regression equations. In this packet you will be calculating different regression equations. (Each problem will tell you which regression equation to calculate) Your calculator will find the equation for you. After we find the equation to represent the points (data), we need to know how well the equation matches the data.
