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 ECL 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

a = 4.3790

b = 0.0008

s = 0.0491

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0008) – 1
= 34.02%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0491) – 1
= 21.68%

Top border of price channel:

Exp(Y453)
= Exp(a + b × X453 + 2 × s)
= Exp(a + b × 658 + 2 × s)
= Exp(4.3790 + 0.0008 × 658 + 2 × 0.0491)
= Exp(5.0051)
= $149.17

Bottom border of price channel:

Exp(Y453)
= Exp(a + b × X453 – 2 × s)
= Exp(a + b × 658 – 2 × s)
= Exp(4.3790 + 0.0008 × 658 – 2 × 0.0491)
= Exp(4.8088)
= $122.58

Top border of price channel:

Exp(Y1,019)
= Exp(a + b × X1,019 + 2 × s)
= Exp(a + b × 1,481 + 2 × s)
= Exp(4.3790 + 0.0008 × 1,481 + 2 × 0.0491)
= Exp(5.6654)
= $288.70

Bottom border of price channel:

Exp(Y1,019)
= Exp(a + b × X1,019 – 2 × s)
= Exp(a + b × 1,481 – 2 × s)
= Exp(4.3790 + 0.0008 × 1,481 – 2 × 0.0491)
= Exp(5.4691)
