### 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 UNM 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 = 2.3856

b = 0.0009

s = 0.1090

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0009) – 1
= 37.88%

Exp(4 × s) – 1
= Exp(4 × 0.1090) – 1
= 54.66%

#### March 9, 2020 calculations

Top border of price channel:

Exp(Y318)
= Exp(a + b × X318 + 2 × s)
= Exp(a + b × 466 + 2 × s)
= Exp(2.3856 + 0.0009 × 466 + 2 × 0.1090)
= Exp(3.0137)
= \$20.36

Bottom border of price channel:

Exp(Y318)
= Exp(a + b × X318 – 2 × s)
= Exp(a + b × 466 – 2 × s)
= Exp(2.3856 + 0.0009 × 466 – 2 × 0.1090)
= Exp(2.5776)
