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 CIEN 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 = -7.4099
b = 0.0070
s = 0.0842
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0070) – 1
= 1,179.02%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0842) – 1
= 40.06%

= $75.33
Bottom border of price channel:
Exp(Y1,138)
= Exp(a + b × X1,138 – 2 × s)
= Exp(a + b × 1,656 – 2 × s)
