### 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 RBA 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 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%

Exp(4 × s) – 1
= Exp(4 × 0.0434) – 1
= 18.98%

#### March 10, 2023 calculations

Top border of price channel:

Exp(Y903)
= Exp(a + b × X903 + 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(Y903)
= Exp(a + b × X903 – 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(Y1,253)
= Exp(a + b × X1,253 + 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(Y1,253)
= Exp(a + b × X1,253 – 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.
• The growth rate of the primary trend is 34.64% per annum.
• RBA price at the close of August 7, 2024 was \$77.30 and was inside the primary price channel.

### Secondary Trend

Start date: February 23, 2024
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%

Exp(4 × s) – 1
= Exp(4 × 0.0314) – 1
= 13.37%

#### February 23, 2024 calculations

Top border of price channel:

Exp(Y1,143)
= Exp(a + b × X1,143 + 2 × s)
= Exp(a + b × 1,660 + 2 × s)
= Exp(3.7627 + 0.0003 × 1,660 + 2 × 0.0314)
= Exp(4.3636)
= \$78.54

Bottom border of price channel:

Exp(Y1,143)
= Exp(a + b × X1,143 – 2 × s)
= Exp(a + b × 1,660 – 2 × s)
= Exp(3.7627 + 0.0003 × 1,660 – 2 × 0.0314)
= Exp(4.2381)
= \$69.28

#### August 7, 2024 calculations

Top border of price channel:

Exp(Y1,257)
= Exp(a + b × X1,257 + 2 × s)
= Exp(a + b × 1,826 + 2 × s)
= Exp(3.7627 + 0.0003 × 1,826 + 2 × 0.0314)
= Exp(4.4174)
= \$82.88

Bottom border of price channel:

Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
= Exp(3.7627 + 0.0003 × 1,826 – 2 × 0.0314)
