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 INSP 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

Start date: September 4, 2024
End date: November 21, 2025
a = 8.7165
b = -0.0025
s = 0.1248
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0025) – 1
= -59.94%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1248) – 1
= 64.71%

Top border of price channel:
Exp(Y882)
= Exp(a + b × X882 + 2 × s)
= Exp(a + b × 1,281 + 2 × s)
= Exp(8.7165 + -0.0025 × 1,281 + 2 × 0.1248)
= Exp(5.7559)
= $316.03
Bottom border of price channel:
Exp(Y882)
= Exp(a + b × X882 – 2 × s)
= Exp(a + b × 1,281 – 2 × s)
= Exp(8.7165 + -0.0025 × 1,281 – 2 × 0.1248)
= Exp(5.2568)
= $191.87
