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 MZTI 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: April 30, 2025
End date: September 3, 2025
a = 3.2787
b = 0.0011
s = 0.0167
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0011) – 1
= 47.48%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0167) – 1
= 6.91%

Top border of price channel:
Exp(Y1,167)
= Exp(a + b × X1,167 + 2 × s)
= Exp(a + b × 1,699 + 2 × s)
= Exp(3.2787 + 0.0011 × 1,699 + 2 × 0.0167)
= Exp(5.1205)
= $167.42
Bottom border of price channel:
Exp(Y1,167)
= Exp(a + b × X1,167 – 2 × s)
= Exp(a + b × 1,699 – 2 × s)
= Exp(3.2787 + 0.0011 × 1,699 – 2 × 0.0167)
= Exp(5.0537)
= $156.59
