Linear regression

Linear regression is an approach in modeling that helps model the scalar linear relationship between a scalar dependent variable, Y, and an independent variable, X, which can be one or more in value:

Let's try to understand this using an example. The following table shows the list of height and weight of students in a class:

Height (inches)

50

125

58

135

63

145

68

70

170

79

165

84

171

75

166

65

160

If we run this through a simple linear regression function, which will be covered in a later chapter, with the weight as a dependent variable, y, and the independent variable, x, which is the height, ...
