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 PPBI 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: March 22, 2023
End date: March 3, 2025
a = 2.5128
b = 0.0004
s = 0.0906
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0004) – 1
= 16.90%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0906) – 1
= 43.67%

Top border of price channel:
Exp(Y644)
= Exp(a + b × X644 + 2 × s)
= Exp(a + b × 936 + 2 × s)
= Exp(2.5128 + 0.0004 × 936 + 2 × 0.0906)
= Exp(3.0943)
= $22.07
Bottom border of price channel:
Exp(Y644)
= Exp(a + b × X644 – 2 × s)
= Exp(a + b × 936 – 2 × s)
= Exp(2.5128 + 0.0004 × 936 – 2 × 0.0906)
= Exp(2.7319)
= $15.36

= Exp(3.3988)
= $29.93
Bottom border of price channel:
Exp(Y1,131)
= Exp(a + b × X1,131 – 2 × s)
= Exp(a + b × 1,648 – 2 × s)
= Exp(2.5128 + 0.0004 × 1,648 – 2 × 0.0906)
= Exp(3.0365)
