Outlier Detection Method in Linear Regression Based on Sum of Arithmetic Progression

Figure 5

Transformation of data to a constant value to overcome the missing data problem, where red diamond corresponds to 𝑦=𝑓(𝑥) form, yellow square corresponds to 𝑦^𝑇=𝑓(𝑥)−𝑓(𝑥₀) form, cross corresponds to 𝑦^′=𝑚∗𝑥_𝑖 form (𝑚=∑^𝑛_𝑖=0𝑦^𝑇_𝑖/∑^𝑛_𝑖=0𝑥^𝑇_𝑖), red circle corresponds to 𝑦^𝑇𝑇=𝑦^𝑇−𝑦^′, and circle corresponds to missing values.
