Flashcards in Multiple regression Deck (9)
What is a linear regression?
Where there is one continuous predictor variable
What is B0?
The intercept, where the line meets the Y axis
What is B1?
The slope, the angle of the regression line
What is the equation for regression as a predictive tool?
Y = B0 + (B1 * X) + (any other predictors)
What are zero order correlations?
Whether there are significant correlations between each individual predictor variable and the outcome
What is the adjusted R squared?
the amount of variance explained by the overall model
What does the B value tell you??
Whether the direction is positive or negative
How do you analyse binary variables?
-The difference between the two groups are always going to be the same
-Regression tells you if the difference from one group to the other is a significant predictor of the outcome
