Is useful (see Sec. 6-12). Solved for a the preceding equation becomes

In fatigue studies a parabola of the Gerber type

This implies a regression model of the form y = a0 + a2x2. Show that the normal equations are

Σ.ry=ao Σ.r+a2 ΣΧ3

And that

ao =ーが3.rm2

Plot the data

20 40 60 80 19 17 13 7

Superposed on a plot of the regression line.

Se .ry=ao .r+a2 3 ao =3.rm2 20 40 60 80 19 17 13 7
