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 NEOG 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: July 11, 2024
End date: August 15, 2025

a = 8.1955

b = -0.0038

s = 0.1393

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0038) – 1
= -75.06%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.1393) – 1
= 74.58%

Top border of price channel:

Exp(Y931)
= Exp(a + b × X931 + 2 × s)
= Exp(a + b × 1,354 + 2 × s)
= Exp(8.1955 + -0.0038 × 1,354 + 2 × 0.1393)
= Exp(3.3231)
= $27.75

Bottom border of price channel:

Exp(Y931)
= Exp(a + b × X931 – 2 × s)
= Exp(a + b × 1,354 – 2 × s)
= Exp(8.1955 + -0.0038 × 1,354 – 2 × 0.1393)
= Exp(2.7659)
= $15.89
