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 11, 2023
End date: January 27, 2025
a = 7.3357
b = -0.0007
s = 0.0417
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0007) – 1
= -22.72%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0417) – 1
= 18.17%

Top border of price channel:
Exp(Y975)
= Exp(a + b × X975 + 2 × s)
= Exp(a + b × 1,413 + 2 × s)
= Exp(7.3357 + -0.0007 × 1,413 + 2 × 0.0417)
= Exp(6.4216)
= $615.01
Bottom border of price channel:
Exp(Y975)
= Exp(a + b × X975 – 2 × s)
= Exp(a + b × 1,413 – 2 × s)
= Exp(7.3357 + -0.0007 × 1,413 – 2 × 0.0417)
= Exp(6.2547)
= $520.44

= Exp(6.1301)
= $459.46
Bottom border of price channel:
Exp(Y1,256)
= Exp(a + b × X1,256 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
