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 SLG 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 = 0.7003
b = 0.0022
s = 0.0962
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0022) – 1
= 119.40%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0962) – 1
= 46.90%

Top border of price channel:
Exp(Y740)
= Exp(a + b × X740 + 2 × s)
= Exp(a + b × 1,073 + 2 × s)
= Exp(0.7003 + 0.0022 × 1,073 + 2 × 0.0962)
= Exp(3.2024)
= $24.59
Bottom border of price channel:
Exp(Y740)
= Exp(a + b × X740 – 2 × s)
= Exp(a + b × 1,073 – 2 × s)
= Exp(0.7003 + 0.0022 × 1,073 – 2 × 0.0962)
= Exp(2.8178)
= $16.74

Top border of price channel:
Exp(Y1,186)
= Exp(a + b × X1,186 + 2 × s)
= Exp(a + b × 1,721 + 2 × s)
= Exp(0.7003 + 0.0022 × 1,721 + 2 × 0.0962)
= Exp(4.5974)
= $99.22
Bottom border of price channel:
Exp(Y1,186)
= Exp(a + b × X1,186 – 2 × s)
= Exp(a + b × 1,721 – 2 × s)
= Exp(0.7003 + 0.0022 × 1,721 – 2 × 0.0962)
= Exp(4.2128)
= $67.54
