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 COHU 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 = -0.2394
b = 0.0020
s = 0.0627
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0020) – 1
= 106.65%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0627) – 1
= 28.53%

Top border of price channel:
Exp(Y1,021)
= Exp(a + b × X1,021 + 2 × s)
= Exp(a + b × 1,484 + 2 × s)
= Exp(-0.2394 + 0.0020 × 1,484 + 2 × 0.0627)
= Exp(2.8372)
= $17.07
Bottom border of price channel:
Exp(Y1,021)
= Exp(a + b × X1,021 – 2 × s)
= Exp(a + b × 1,484 – 2 × s)
= Exp(-0.2394 + 0.0020 × 1,484 – 2 × 0.0627)
= Exp(2.5862)
= $13.28
