General Linear Model Flashcards
1
Q
Why is the general linear model important?
A
A common mathematical foundation of several statistical models: all the ANOVAS, regression, t-test, f-test
Developed for outcome variables that are roughly normally distributed
2
Q
What is the equation for the general linear model?
A
Yi = β0 + β1X1i + εi
3
Q
Yi
A
the value of the DV (aka expected value)
4
Q
i
A
indicates we are dealing with 1 score or case
5
Q
β0
A
intercept term, constant; value of Y when all X equal zero
6
Q
β1
A
regression coefficient for variable X; how much does X influence Y
7
Q
X1i
A
score of x for person or case 1
8
Q
εi
A
residual, error term; how far the person’s score is from expected score; score of deviance
