### 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: February 17, 2023

End date: July 25, 2024

a = 6.8158

b = -0.0020

s = 0.0899

Annual growth rate:

Exp(365 × b) – 1

= Exp(365 × -0.0020) – 1

= -51.99%

Price channel spread:

Exp(4 × s) – 1

= Exp(4 × 0.0899) – 1

= 43.28%

#### February 17, 2023 calculations

Top border of price channel:

Exp(Y_{885})

= Exp(a + b × X_{885} + 2 × s)

= Exp(a + b × 1,283 + 2 × s)

= Exp(6.8158 + -0.0020 × 1,283 + 2 × 0.0899)

= Exp(4.4167)

= $82.82

Bottom border of price channel:

Exp(Y_{885})

= Exp(a + b × X_{885} – 2 × s)

= Exp(a + b × 1,283 – 2 × s)

= Exp(6.8158 + -0.0020 × 1,283 – 2 × 0.0899)

= Exp(4.0571)

= $57.80

#### July 25, 2024 calculations

Top border of price channel:

Exp(Y_{1,244})

= Exp(a + b × X_{1,244} + 2 × s)

= Exp(a + b × 1,807 + 2 × s)

= Exp(6.8158 + -0.0020 × 1,807 + 2 × 0.0899)

= Exp(3.3634)

= $28.89

Bottom border of price channel:

Exp(Y_{1,244})

= Exp(a + b × X_{1,244} – 2 × s)

= Exp(a + b × 1,807 – 2 × s)

= Exp(6.8158 + -0.0020 × 1,807 – 2 × 0.0899)

= Exp(3.0038)

= $20.16

#### Description

- The primary trend is decreasing.

a = 3.6092

b = -0.0002

s = 0.0673

Annual growth rate:

Exp(365 × b) – 1

= Exp(365 × -0.0002) – 1

= -5.92%
