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 UNFI 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, 2024
End date: March 3, 2025
a = -3.2419
b = 0.0038
s = 0.0950
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0038) – 1
= 302.58%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0950) – 1
= 46.21%

Top border of price channel:
Exp(Y980)
= Exp(a + b × X980 + 2 × s)
= Exp(a + b × 1,422 + 2 × s)
= Exp(-3.2419 + 0.0038 × 1,422 + 2 × 0.0950)
= Exp(2.3740)
= $10.74
Bottom border of price channel:
Exp(Y980)
= Exp(a + b × X980 – 2 × s)
= Exp(a + b × 1,422 – 2 × s)
= Exp(-3.2419 + 0.0038 × 1,422 – 2 × 0.0950)
= Exp(1.9941)
= $7.35

= Exp(3.6942)
= $40.21
Bottom border of price channel:
Exp(Y1,215)
= Exp(a + b × X1,215 – 2 × s)
= Exp(a + b × 1,768 – 2 × s)
= Exp(-3.2419 + 0.0038 × 1,768 – 2 × 0.0950)
= Exp(3.3144)
