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 STBA 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 = 2.4945
b = 0.0008
s = 0.0835
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0008) – 1
= 33.73%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0835) – 1
= 39.65%
