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 VTOL 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: December 4, 2020
End date: May 7, 2024
a = 3.4299
b = -0.0001
s = 0.1165
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0001) – 1
= -3.63%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1165) – 1
= 59.36%

Top border of price channel:
Exp(Y261)
= Exp(a + b × X261 + 2 × s)
= Exp(a + b × 379 + 2 × s)
= Exp(3.4299 + -0.0001 × 379 + 2 × 0.1165)
= Exp(3.6245)
= $37.51
Bottom border of price channel:
Exp(Y261)
= Exp(a + b × X261 – 2 × s)
= Exp(a + b × 379 – 2 × s)
= Exp(3.4299 + -0.0001 × 379 – 2 × 0.1165)
= Exp(3.1585)
= $23.54

Top border of price channel:
Exp(Y1,120)
= Exp(a + b × X1,120 + 2 × s)
= Exp(a + b × 1,629 + 2 × s)
= Exp(3.4299 + -0.0001 × 1,629 + 2 × 0.1165)
= Exp(3.4979)
= $33.04
Bottom border of price channel:
Exp(Y1,120)
= Exp(a + b × X1,120 – 2 × s)
= Exp(a + b × 1,629 – 2 × s)
= Exp(3.4299 + -0.0001 × 1,629 – 2 × 0.1165)
= Exp(3.0319)
= $20.74
