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 WY 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
Primary Trend
Start date: March 31, 2021
End date: April 29, 2025
a = 3.4852
b = -0.0001
s = 0.0757
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0001) – 1
= -1.98%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0757) – 1
= 35.37%

Top border of price channel:
Exp(Y231)
= Exp(a + b × X231 + 2 × s)
= Exp(a + b × 335 + 2 × s)
= Exp(3.4852 + -0.0001 × 335 + 2 × 0.0757)
= Exp(3.6182)
= $37.27
Bottom border of price channel:
Exp(Y231)
= Exp(a + b × X231 – 2 × s)
= Exp(a + b × 335 – 2 × s)
= Exp(3.4852 + -0.0001 × 335 – 2 × 0.0757)
= Exp(3.3154)
= $27.53

= Exp(3.5365)
= $34.34
Bottom border of price channel:
Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
