Presentation Transcript

### Statistical Valentine

Hamburger Fold Card

• Add those “residuals” to a deterministic equation like:

y = 100 + 25x + resid.

• This scrunches up the residuals and obscures pattern.
• Calculator: x-values L1

y-value (residuals) L2

100 + 25L1 + L2 L3

• Then regress L3 on L1.
