2.1. The derivative and slope
A derivative is a function
It is a rate of change of a function
It is the slope of the line tangent to the curve
Differentiation is all about measuring a change in a

Chapter 9: Estimation of Multiple
Linear Regression Models
It examines the linear relationship between a dependent
variable and at least 2 independent variables (Xi).
Multiple Regression Model with k Independent Variables:
Y-intercept
Population slopes

Chapter 10: Problems of Measurement,
Specification, Estimation and Their Solutions
Before any regression, it is worthy of doing
some additional scrutiny because a badly
misspecified model may lead to erroneous
inferences.
Hence, the following tests are

Chapter 8: Estimation of two variables
Regression Model
The relationships among various economic
variables are shown by economic theories.
The relationship between two variables
related in a linear form is called simple linear
regression model.
