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 ABBV 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

End date: December 29, 2023
a = 4.7900
b = 0.0001
s = 0.0584
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0001) – 1
= 4.33%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0584) – 1
= 26.29%

Top border of price channel:
Exp(Y476)
= Exp(a + b × X476 + 2 × s)
= Exp(a + b × 687 + 2 × s)
= Exp(4.7900 + 0.0001 × 687 + 2 × 0.0584)
= Exp(4.9864)
= $146.41
Bottom border of price channel:
Exp(Y476)
= Exp(a + b × X476 – 2 × s)
= Exp(a + b × 687 – 2 × s)
= Exp(4.7900 + 0.0001 × 687 – 2 × 0.0584)
= Exp(4.7530)
= $115.93

Top border of price channel:
Exp(Y988)
= Exp(a + b × X988 + 2 × s)
= Exp(a + b × 1,431 + 2 × s)
= Exp(4.7900 + 0.0001 × 1,431 + 2 × 0.0584)
= Exp(5.0728)
= $159.61
Bottom border of price channel:
Exp(Y988)
= Exp(a + b × X988 – 2 × s)
= Exp(a + b × 1,431 – 2 × s)
= Exp(4.7900 + 0.0001 × 1,431 – 2 × 0.0584)
= Exp(4.8394)
