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
Primary Trend
Start date: March 6, 2024
End date: March 6, 2025
a = -2.5450
b = 0.0035
s = 0.1139
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0035) – 1
= 263.59%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1139) – 1
= 57.71%

Top border of price channel:
Exp(Y922)
= Exp(a + b × X922 + 2 × s)
= Exp(a + b × 1,338 + 2 × s)
= Exp(-2.5450 + 0.0035 × 1,338 + 2 × 0.1139)
= Exp(2.4148)
= $11.19
Bottom border of price channel:
Exp(Y922)
= Exp(a + b × X922 – 2 × s)
= Exp(a + b × 1,338 – 2 × s)
= Exp(-2.5450 + 0.0035 × 1,338 – 2 × 0.1139)
= Exp(1.9593)
= $7.09

= Exp(3.7057)
= $40.68
Bottom border of price channel:
Exp(Y1,172)
= Exp(a + b × X1,172 – 2 × s)
= Exp(a + b × 1,703 – 2 × s)
