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 TILE 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: May 17, 2024
a = -1.0180
b = 0.0021
s = 0.0817
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0021) – 1
= 114.31%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0817) – 1
= 38.66%

Top border of price channel:
Exp(Y976)
= Exp(a + b × X976 + 2 × s)
= Exp(a + b × 1,415 + 2 × s)
= Exp(-1.0180 + 0.0021 × 1,415 + 2 × 0.0817)
= Exp(2.1005)
= $8.17
Bottom border of price channel:
Exp(Y976)
= Exp(a + b × X976 – 2 × s)
= Exp(a + b × 1,415 – 2 × s)
= Exp(-1.0180 + 0.0021 × 1,415 – 2 × 0.0817)
= Exp(1.7737)
= $5.89
