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 BDN 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: March 16, 2023
End date: July 25, 2024

a = 0.4892

b = 0.0006

s = 0.0927

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0006) – 1
= 23.36%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0927) – 1
= 44.89%

Top border of price channel:

Exp(Y916)
= Exp(a + b × X916 + 2 × s)
= Exp(a + b × 1,329 + 2 × s)
= Exp(0.4892 + 0.0006 × 1,329 + 2 × 0.0927)
= Exp(1.4391)
= $4.22

Bottom border of price channel:

Exp(Y916)
= Exp(a + b × X916 – 2 × s)
= Exp(a + b × 1,329 – 2 × s)
= Exp(0.4892 + 0.0006 × 1,329 – 2 × 0.0927)
= Exp(1.0683)
= $2.91

= Exp(1.7250)
= $5.61

Bottom border of price channel:

Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
