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 WDFC 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 = 4.4241
b = 0.0007
s = 0.0711
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0007) – 1
= 28.78%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0711) – 1
= 32.89%

Top border of price channel:
Exp(Y640)
= Exp(a + b × X640 + 2 × s)
= Exp(a + b × 928 + 2 × s)
= Exp(4.4241 + 0.0007 × 928 + 2 × 0.0711)
= Exp(5.2093)
= $182.97
Bottom border of price channel:
Exp(Y640)
= Exp(a + b × X640 – 2 × s)
= Exp(a + b × 928 – 2 × s)
= Exp(4.4241 + 0.0007 × 928 – 2 × 0.0711)
= Exp(4.9249)
= $137.68
