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 CSGS 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 = 2.3614
b = 0.0011
s = 0.0592
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0011) – 1
= 47.82%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0592) – 1
= 26.71%

Top border of price channel:
Exp(Y858)
= Exp(a + b × X858 + 2 × s)
= Exp(a + b × 1,247 + 2 × s)
= Exp(2.3614 + 0.0011 × 1,247 + 2 × 0.0592)
= Exp(3.8149)
= $45.37
Bottom border of price channel:
Exp(Y858)
= Exp(a + b × X858 – 2 × s)
= Exp(a + b × 1,247 – 2 × s)
= Exp(2.3614 + 0.0011 × 1,247 – 2 × 0.0592)
= Exp(3.5782)
= $35.81
