### 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 RBA 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: March 10, 2023

End date: August 1, 2024

a = 2.8931

b = 0.0008

s = 0.0434

Annual growth rate:

Exp(365 × b) – 1

= Exp(365 × 0.0008) – 1

= 34.64%

Price channel spread:

Exp(4 × s) – 1

= Exp(4 × 0.0434) – 1

= 18.98%

#### March 10, 2023 calculations

Top border of price channel:

Exp(Y_{903})

= Exp(a + b × X_{903} + 2 × s)

= Exp(a + b × 1,310 + 2 × s)

= Exp(2.8931 + 0.0008 × 1,310 + 2 × 0.0434)

= Exp(4.0475)

= $57.25

Bottom border of price channel:

Exp(Y_{903})

= Exp(a + b × X_{903} – 2 × s)

= Exp(a + b × 1,310 – 2 × s)

= Exp(2.8931 + 0.0008 × 1,310 – 2 × 0.0434)

= Exp(3.8737)

= $48.12

#### August 1, 2024 calculations

Top border of price channel:

Exp(Y_{1,253})

= Exp(a + b × X_{1,253} + 2 × s)

= Exp(a + b × 1,820 + 2 × s)

= Exp(2.8931 + 0.0008 × 1,820 + 2 × 0.0434)

= Exp(4.4631)

= $86.75

Bottom border of price channel:

Exp(Y_{1,253})

= Exp(a + b × X_{1,253} – 2 × s)

= Exp(a + b × 1,820 – 2 × s)

= Exp(2.8931 + 0.0008 × 1,820 – 2 × 0.0434)

= Exp(4.2893)

= $72.91

#### Description

- The primary trend is increasing.

End date: August 7, 2024

a = 3.7627

b = 0.0003

s = 0.0314

Annual growth rate:

Exp(365 × b) – 1

= Exp(365 × 0.0003) – 1

= 12.56%
