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 PZZA 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: July 9, 2021
End date: July 26, 2024
a = 5.2694
b = -0.0007
s = 0.1158
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0007) – 1
= -22.51%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1158) – 1
= 58.92%

Top border of price channel:
Exp(Y491)
= Exp(a + b × X491 + 2 × s)
= Exp(a + b × 711 + 2 × s)
= Exp(5.2694 + -0.0007 × 711 + 2 × 0.1158)
= Exp(5.0042)
= $149.04
Bottom border of price channel:
Exp(Y491)
= Exp(a + b × X491 – 2 × s)
= Exp(a + b × 711 – 2 × s)
= Exp(5.2694 + -0.0007 × 711 – 2 × 0.1158)
= Exp(4.5410)
= $93.78

Exp(Y1,257)
= Exp(a + b × X1,257 + 2 × s)
= Exp(a + b × 1,824 + 2 × s)
= Exp(5.2694 + -0.0007 × 1,824 + 2 × 0.1158)
= Exp(4.2264)
= $68.47
Bottom border of price channel:
Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,824 – 2 × s)
= Exp(5.2694 + -0.0007 × 1,824 – 2 × 0.1158)
= Exp(3.7631)
