So then why do we care about multicollinearity? 2. The variances and the standard errors of the regression coefficient estimates will increase. This means lower t-statistics. 3. The overall fit of the regression equation will be largely unaffected by multicollinearity. rsnetworx identity mismatch

"WebSlope is the change in y/change in x; the same thing as rise/run. Here is an example: Lets say you have a equation that says y=1/4x+2. Its pretty simple from there. So, we know in the slope intercept formula (y=mx+b) we know that m=slope and b=y intercept. So for the equation I gave you m=1/4 and b=2. So, from the y-intercept (which is 2) you ...
