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 IDXX 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
Primary Trend
Start date: December 8, 2023
End date: April 17, 2025
a = 7.1770
b = -0.0006
s = 0.0444
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0006) – 1
= -20.79%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0444) – 1
= 19.43%

Top border of price channel:
Exp(Y916)
= Exp(a + b × X916 + 2 × s)
= Exp(a + b × 1,326 + 2 × s)
= Exp(7.1770 + -0.0006 × 1,326 + 2 × 0.0444)
= Exp(6.4190)
= $613.40
Bottom border of price channel:
Exp(Y916)
= Exp(a + b × X916 – 2 × s)
= Exp(a + b × 1,326 – 2 × s)
= Exp(7.1770 + -0.0006 × 1,326 – 2 × 0.0444)
= Exp(6.2414)
= $513.60

= Exp(6.1023)
= $446.87
Bottom border of price channel:
Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,822 – 2 × s)
