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 KOP 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: January 19, 2024
End date: November 5, 2024
a = 6.7176
b = -0.0018
s = 0.0742
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0018) – 1
= -47.68%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0742) – 1
= 34.54%

Top border of price channel:
Exp(Y1,045)
= Exp(a + b × X1,045 + 2 × s)
= Exp(a + b × 1,520 + 2 × s)
= Exp(6.7176 + -0.0018 × 1,520 + 2 × 0.0742)
= Exp(4.1684)
= $64.61
Bottom border of price channel:
Exp(Y1,045)
= Exp(a + b × X1,045 – 2 × s)
= Exp(a + b × 1,520 – 2 × s)
= Exp(6.7176 + -0.0018 × 1,520 – 2 × 0.0742)
= Exp(3.8717)
= $48.02

= Exp(6.7176 + -0.0018 × 1,811 + 2 × 0.0742)
= Exp(3.6519)
= $38.55
Bottom border of price channel:
Exp(Y1,246)
= Exp(a + b × X1,246 – 2 × s)
= Exp(a + b × 1,811 – 2 × s)
