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 LUV 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 = 4.4188
b = -0.0008
s = 0.0681
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0008) – 1
= -25.65%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0681) – 1
= 31.31%

Top border of price channel:
Exp(Y304)
= Exp(a + b × X304 + 2 × s)
= Exp(a + b × 443 + 2 × s)
= Exp(4.4188 + -0.0008 × 443 + 2 × 0.0681)
= Exp(4.1952)
= $66.37
Bottom border of price channel:
Exp(Y304)
= Exp(a + b × X304 – 2 × s)
= Exp(a + b × 443 – 2 × s)
= Exp(4.4188 + -0.0008 × 443 – 2 × 0.0681)
= Exp(3.9228)
= $50.54

Top border of price channel:
Exp(Y895)
= Exp(a + b × X895 + 2 × s)
= Exp(a + b × 1,301 + 2 × s)
= Exp(4.4188 + -0.0008 × 1,301 + 2 × 0.0681)
= Exp(3.4984)
= $33.06
Bottom border of price channel:
Exp(Y895)
= Exp(a + b × X895 – 2 × s)
= Exp(a + b × 1,301 – 2 × s)
= Exp(4.4188 + -0.0008 × 1,301 – 2 × 0.0681)
= Exp(3.2260)
