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 IRWD 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: June 21, 2021
End date: December 12, 2023

a = 2.8040

b = -0.0003

s = 0.0618

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0003) – 1
= -10.83%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0618) – 1
= 28.02%

June 21, 2021 calculations

Top border of price channel:

Exp(Y532)
= Exp(a + b × X532 + 2 × s)
= Exp(a + b × 773 + 2 × s)
= Exp(2.8040 + -0.0003 × 773 + 2 × 0.0618)
= Exp(2.6847)
= $14.65

Bottom border of price channel:

Exp(Y532)
= Exp(a + b × X532 – 2 × s)
= Exp(a + b × 773 – 2 × s)
= Exp(2.8040 + -0.0003 × 773 – 2 × 0.0618)
= Exp(2.4377)
= $11.45

Top border of price channel:

Exp(Y1,156)
= Exp(a + b × X1,156 + 2 × s)
= Exp(a + b × 1,677 + 2 × s)
= Exp(2.8040 + -0.0003 × 1,677 + 2 × 0.0618)
= Exp(2.4008)
= $11.03

Bottom border of price channel:

Exp(Y1,156)
= Exp(a + b × X1,156 – 2 × s)
= Exp(a + b × 1,677 – 2 × s)
= Exp(2.8040 + -0.0003 × 1,677 – 2 × 0.0618)
= Exp(2.1538)
= $8.62
