Multiple Regression | Rate this: (3/5 from 1 vote) |
 | Hello I'm not that good in math and i have searched through the internet but came out way confused than before. i would like to know in multiple regression, how does one know when to add another independent variable? do you have to test it in a simple liner regression first then transfer it to a multiple regression? Is it possible to test whether a variable that i added have any relationshipwith the rest of the variable by using some equations? in plotting multiple regression is it usually in a 3d space? how about if you have more than 3 variables how will my graph look? please help me thanks in advance | |

| Rate this: (3/5 from 1 vote) i want to do a multiple regression on let's say voter's behavior then i arrive at a formula voter's behavior = B0 + B1X1+ B2X2 + B3X3 my question is this. should all regression start off as linear regression? meaning that i should add variable one at a time? if so and i have 3 independent variable i wanted to add and i want to test the residuals and coefficient of each one, should i convert them to linear regression? like this voter's behavior = B0 + B1X1 voter's behavior = B0 + B2X2 voter's behavior = B0 + B3X3 or does multiple regression have a different approach? |
