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 RCUS 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 = -12.1787

b = 0.0085

s = 0.0527

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0085) – 1
= 2,109.86%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0527) – 1
= 23.46%
