Linear regression Flashcards
1
Q
can be used to develop an
equation showing how the variables are related
A
Regression analysis
2
Q
The variable being predicted is called the
A
dependent
variable and is denoted by y.
3
Q
The variables being used to predict the value of the
dependent variable are called the
A
independent
variables
4
Q
involves one independent
variable and one dependent variable.
A
Simple linear regression
5
Q
Regression analysis involving two or more
independent variables is called
A
multiple regression
6
Q
The equation that describes how y is related to x and
an error term is called the
A
regression model
7
Q
b0 and
b1 are called
A
parameters of the model
8
Q
e is a random variable called the
A
error term
9
Q
is the slope of the line.
A
b1

Q
is the y intercept of the line.
