Regression
The relationship between two variables is modeled through Simple linear regression, wherein it can be precisely estimated how much Y will change when X changes by a specific amount. With regression, one tries to establish a linear relationship between the two chosen variables.
Y=b0+b1.X
Wherein:
Y: Target
b0:Constant or Intercept
b1:Slope
X: Feature Vector
b0 and b1both appear in R output as coefficients.
