Linear Regression Model
Model equation:
Yi = α + β × Xi + εi
Top border of price channel:
Exp(Yi) = Exp(a + b × Xi + 2 × s)
Bottom border of price channel:
Exp(Yi) = Exp(a + b × Xi – 2 × s)
where:
i - observation number
Yi - natural logarithm of EBAY price
Xi - time index, 1 day interval
σ - standard deviation of εi
a - estimator of α
b - estimator of β
s - estimator of σ
Exp() - calculates the exponent of e

a = 2.2562
b = 0.0011
s = 0.0517
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0011) – 1
= 50.71%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0517) – 1
= 22.97%

Top border of price channel:
Exp(Y856)
= Exp(a + b × X856 + 2 × s)
= Exp(a + b × 1,241 + 2 × s)
= Exp(2.2562 + 0.0011 × 1,241 + 2 × 0.0517)
= Exp(3.7542)
= $42.70
Bottom border of price channel:
Exp(Y856)
= Exp(a + b × X856 – 2 × s)
= Exp(a + b × 1,241 – 2 × s)
= Exp(2.2562 + 0.0011 × 1,241 – 2 × 0.0517)
= Exp(3.5474)
= $34.72
