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 UNF 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 = 4.6758
b = 0.0003
s = 0.0658
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0003) – 1
= 13.34%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0658) – 1
= 30.10%

Top border of price channel:
Exp(Y737)
= Exp(a + b × X737 + 2 × s)
= Exp(a + b × 1,069 + 2 × s)
= Exp(4.6758 + 0.0003 × 1,069 + 2 × 0.0658)
= Exp(5.1740)
= $176.63
Bottom border of price channel:
Exp(Y737)
= Exp(a + b × X737 – 2 × s)
= Exp(a + b × 1,069 – 2 × s)
= Exp(4.6758 + 0.0003 × 1,069 – 2 × 0.0658)
= Exp(4.9109)
= $135.76
