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: October 19, 2022
End date: October 28, 2025
a = 4.3339
b = 0.0004
s = 0.1361
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0004) – 1
= 16.88%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1361) – 1
= 72.38%

Top border of price channel:
Exp(Y496)
= Exp(a + b × X496 + 2 × s)
= Exp(a + b × 720 + 2 × s)
= Exp(4.3339 + 0.0004 × 720 + 2 × 0.1361)
= Exp(4.9138)
= $136.16
Bottom border of price channel:
Exp(Y496)
= Exp(a + b × X496 – 2 × s)
= Exp(a + b × 720 – 2 × s)
= Exp(4.3339 + 0.0004 × 720 – 2 × 0.1361)
= Exp(4.3693)
= $78.99

Bottom border of price channel:
Exp(Y1,254)
= Exp(a + b × X1,254 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
