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 PPG 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

Start date: November 30, 2023
End date: August 23, 2024
a = 5.9785
b = -0.0007
s = 0.0229
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0007) – 1
= -21.86%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0229) – 1
= 9.60%

Top border of price channel:
Exp(Y1,012)
= Exp(a + b × X1,012 + 2 × s)
= Exp(a + b × 1,470 + 2 × s)
= Exp(5.9785 + -0.0007 × 1,470 + 2 × 0.0229)
= Exp(5.0308)
= $153.06
Bottom border of price channel:
Exp(Y1,012)
= Exp(a + b × X1,012 – 2 × s)
= Exp(a + b × 1,470 – 2 × s)
= Exp(5.9785 + -0.0007 × 1,470 – 2 × 0.0229)
= Exp(4.9392)
= $139.66

= Exp(5.9785 + -0.0007 × 1,737 + 2 × 0.0229)
= Exp(4.8504)
= $127.79
Bottom border of price channel:
Exp(Y1,195)
= Exp(a + b × X1,195 – 2 × s)
= Exp(a + b × 1,737 – 2 × s)
= Exp(5.9785 + -0.0007 × 1,737 – 2 × 0.0229)
= Exp(4.7587)
