### Linear Regression Model

Model equation:

Y_{i} = α + β × X_{i} + ε_{i}

Top border of price channel:

Exp(Y_{i}) = Exp(a + b × X_{i} + 2 × s)

Bottom border of price channel:

Exp(Y_{i}) = Exp(a + b × X_{i} – 2 × s)

where:

i - observation number

Y_{i} - natural logarithm of IRDM price

X_{i} - time index, 1 day interval

σ - standard deviation of ε_{i}

a - estimator of α

b - estimator of β

s - estimator of σ

Exp() - calculates the exponent of e

### Primary Trend

Start date: April 20, 2023

End date: March 1, 2024

a = 7.8486

b = -0.0024

s = 0.0674

Annual growth rate:

Exp(365 × b) – 1

= Exp(365 × -0.0024) – 1

= -58.52%

Price channel spread:

Exp(4 × s) – 1

= Exp(4 × 0.0674) – 1

= 30.93%

#### April 20, 2023 calculations

Top border of price channel:

Exp(Y_{1,041})

= Exp(a + b × X_{1,041} + 2 × s)

= Exp(a + b × 1,508 + 2 × s)

= Exp(7.8486 + -0.0024 × 1,508 + 2 × 0.0674)

= Exp(4.3477)

= $77.30

Bottom border of price channel:
