Which of the following statements is true regarding the error in linear regression between the original data and the fitted line?

It is the vertical distance between the datapoint and the model

It is the distance between the datapoint and the model that is perpendicular to the fitted line’s gradient

It is the averaged distance between the datapoint and the model

It is the horizontal distance between the datapoint and the model

Which of the following equations represents the linearised version of the following power model?

H = γx^(4πω)

log(H) = xlog(4πω) + γ

log10(H) = log10(γ) + 4πω log10(x)

log10(H) = xlog10(γ) + 4πω

log(H) = γlog(4πω) + x

Which of the following equations represents the linearised version of the following saturation-growth model?

θ = (k^2*x)/(σ+x)

1/θ = σx/k^2 + 1/k^2

θ = k^2/(σx) + k^2

1/θ = σ/(k^2*x) + 1/k^2

1/θ = k^2/(σx) + 1/k^2

Which of the following equations represents the linearised version of the following exponential model?

H = μe^(2δL)

log⁡(H)/2 = log(δL) + μ

log⁡(H) = μlog(2δ) + 2L

log⁡(H) = 2log(μ) + δL

log⁡(H) = log(μ) + 2δL
