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 PRGO 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

Start date: June 18, 2024
End date: July 25, 2024
a = -1.9069
b = 0.0029
s = 0.0166
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0029) – 1
= 185.04%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0166) – 1
= 6.88%

Top border of price channel:
Exp(Y1,232)
= Exp(a + b × X1,232 + 2 × s)
= Exp(a + b × 1,789 + 2 × s)
= Exp(-1.9069 + 0.0029 × 1,789 + 2 × 0.0166)
= Exp(3.2604)
= $26.06
Bottom border of price channel:
Exp(Y1,232)
= Exp(a + b × X1,232 – 2 × s)
= Exp(a + b × 1,789 – 2 × s)
= Exp(-1.9069 + 0.0029 × 1,789 – 2 × 0.0166)
= Exp(3.1939)
= $24.38

= Exp(3.3666)
= $28.98
Bottom border of price channel:
Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
