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 GNRC 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: September 18, 2023
End date: November 19, 2024
a = 2.8677
b = 0.0012
s = 0.0732
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0012) – 1
= 57.63%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0732) – 1
= 34.02%

Top border of price channel:
Exp(Y961)
= Exp(a + b × X961 + 2 × s)
= Exp(a + b × 1,398 + 2 × s)
= Exp(2.8677 + 0.0012 × 1,398 + 2 × 0.0732)
= Exp(4.7571)
= $116.41
Bottom border of price channel:
Exp(Y961)
= Exp(a + b × X961 – 2 × s)
= Exp(a + b × 1,398 – 2 × s)
= Exp(2.8677 + 0.0012 × 1,398 – 2 × 0.0732)
= Exp(4.4643)
= $86.86

= Exp(5.2907)
= $198.49
Bottom border of price channel:
Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
