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 IART 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: November 30, 2022
End date: November 19, 2024
a = 5.8280
b = -0.0015
s = 0.1355
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0015) – 1
= -42.39%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1355) – 1
= 71.96%

Top border of price channel:
Exp(Y762)
= Exp(a + b × X762 + 2 × s)
= Exp(a + b × 1,106 + 2 × s)
= Exp(5.8280 + -0.0015 × 1,106 + 2 × 0.1355)
= Exp(4.4280)
= $83.76
Bottom border of price channel:
Exp(Y762)
= Exp(a + b × X762 – 2 × s)
= Exp(a + b × 1,106 – 2 × s)
= Exp(5.8280 + -0.0015 × 1,106 – 2 × 0.1355)
= Exp(3.8859)
= $48.71

Top border of price channel:
Exp(Y1,257)
= Exp(a + b × X1,257 + 2 × s)
= Exp(a + b × 1,826 + 2 × s)
= Exp(5.8280 + -0.0015 × 1,826 + 2 × 0.1355)
= Exp(3.3401)
= $28.22
Bottom border of price channel:
Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
= Exp(5.8280 + -0.0015 × 1,826 – 2 × 0.1355)
= Exp(2.7980)
= $16.41
