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 PI 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 = -1.9584
b = 0.0042
s = 0.1347
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0042) – 1
= 363.11%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1347) – 1
= 71.40%

Top border of price channel:
Exp(Y1,025)
= Exp(a + b × X1,025 + 2 × s)
= Exp(a + b × 1,491 + 2 × s)
= Exp(-1.9584 + 0.0042 × 1,491 + 2 × 0.1347)
= Exp(4.5724)
= $96.78
Bottom border of price channel:
Exp(Y1,025)
= Exp(a + b × X1,025 – 2 × s)
= Exp(a + b × 1,491 – 2 × s)
= Exp(-1.9584 + 0.0042 × 1,491 – 2 × 0.1347)
= Exp(4.0336)
= $56.46
