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 GME 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

a = 4.2817
b = -0.0012
s = 0.1768
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0012) – 1
= -36.10%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1768) – 1
= 102.83%

Top border of price channel:
Exp(Y165)
= Exp(a + b × X165 + 2 × s)
= Exp(a + b × 242 + 2 × s)
= Exp(4.2817 + -0.0012 × 242 + 2 × 0.1768)
= Exp(4.3383)
= $76.58
Bottom border of price channel:
Exp(Y165)
= Exp(a + b × X165 – 2 × s)
= Exp(a + b × 242 – 2 × s)
= Exp(4.2817 + -0.0012 × 242 – 2 × 0.1768)
= Exp(3.6312)
= $37.76

Top border of price channel:
Exp(Y968)
= Exp(a + b × X968 + 2 × s)
= Exp(a + b × 1,406 + 2 × s)
= Exp(4.2817 + -0.0012 × 1,406 + 2 × 0.1768)
= Exp(2.9100)
= $18.36
Bottom border of price channel:
Exp(Y968)
= Exp(a + b × X968 – 2 × s)
= Exp(a + b × 1,406 – 2 × s)
= Exp(4.2817 + -0.0012 × 1,406 – 2 × 0.1768)
= Exp(2.2029)
