Prediction from a linear model · formula reference
A model prediction is not a guarantee about an individual outcome.
Formula
A model prediction is not a guarantee about an individual outcome.
ŷ = wx + b
Worked example
A fitted linear model has w=6, b=-19. Find its prediction at x=11. Round the final result to 4 decimal places if needed.
Substitute into ŷ=wx+b: (6)(11)+(-19).
