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

End date: April 9, 2024
a = 3.9919
b = 0.0010
s = 0.0566
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0010) – 1
= 43.00%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0566) – 1
= 25.42%

Top border of price channel:
Exp(Y718)
= Exp(a + b × X718 + 2 × s)
= Exp(a + b × 1,043 + 2 × s)
= Exp(3.9919 + 0.0010 × 1,043 + 2 × 0.0566)
= Exp(5.1273)
= $168.56
Bottom border of price channel:
Exp(Y718)
= Exp(a + b × X718 – 2 × s)
= Exp(a + b × 1,043 – 2 × s)
= Exp(3.9919 + 0.0010 × 1,043 – 2 × 0.0566)
= Exp(4.9008)
= $134.40

= Exp(3.9919 + 0.0010 × 1,601 + 2 × 0.0566)
= Exp(5.6741)
= $291.23
Bottom border of price channel:
Exp(Y1,100)
= Exp(a + b × X1,100 – 2 × s)
= Exp(a + b × 1,601 – 2 × s)
= Exp(3.9919 + 0.0010 × 1,601 – 2 × 0.0566)
= Exp(5.4476)
