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 DAR 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

End date: June 12, 2025
a = 4.9144
b = -0.0008
s = 0.0956
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0008) – 1
= -25.96%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0956) – 1
= 46.60%

Top border of price channel:
Exp(Y417)
= Exp(a + b × X417 + 2 × s)
= Exp(a + b × 603 + 2 × s)
= Exp(4.9144 + -0.0008 × 603 + 2 × 0.0956)
= Exp(4.6090)
= $100.39
Bottom border of price channel:
Exp(Y417)
= Exp(a + b × X417 – 2 × s)
= Exp(a + b × 603 – 2 × s)
= Exp(4.9144 + -0.0008 × 603 – 2 × 0.0956)
= Exp(4.2265)
= $68.48

Top border of price channel:
Exp(Y1,241)
= Exp(a + b × X1,241 + 2 × s)
= Exp(a + b × 1,802 + 2 × s)
= Exp(4.9144 + -0.0008 × 1,802 + 2 × 0.0956)
= Exp(3.6216)
= $37.40
Bottom border of price channel:
Exp(Y1,241)
= Exp(a + b × X1,241 – 2 × s)
= Exp(a + b × 1,802 – 2 × s)
= Exp(4.9144 + -0.0008 × 1,802 – 2 × 0.0956)
= Exp(3.2391)
