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 VRSN 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 = 1.4143

b = 0.0023

s = 0.0176

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0023) – 1
= 131.75%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0176) – 1
= 7.30%

Top border of price channel:

Exp(Y1,123)
= Exp(a + b × X1,123 + 2 × s)
= Exp(a + b × 1,628 + 2 × s)
= Exp(1.4143 + 0.0023 × 1,628 + 2 × 0.0176)
= Exp(5.1984)
= $180.99

Bottom border of price channel:

Exp(Y1,123)
= Exp(a + b × X1,123 – 2 × s)
= Exp(a + b × 1,628 – 2 × s)
