Colinear Definition & Meaning - Merriam-Webster

Collinearity occurs because independent variables that we use to build a regression model are correlated with each other. This is problematic because as the name suggests, an independent variable should be independent. It shouldn’t have any correlation with other independent variables. If collinearity exists … See more There are several things how collinearity would affect our model, which are: 1. The coefficient estimates of independent variables would be very sensitive to the change in the model, … See more The first one is by looking at the correlation matrix of our independent variables. The rule of thumb is that if two independent variables have a Pearson’s correlation above 0.9, then we can say that both … See more Now that we know severe collinearity exists in our independent variables, we need to find a way to fix this. There are two common ways to remove collinearity. See more Variance Inflation Factor or VIF measures the influence of collinearity on the variance of our coefficient estimates.

The collinearity equations are a set of two equations, used in photogrammetry and computer stereo vision, to relate coordinates in a sensor plane (in two dimensions) to object coordinates (in three dimensions). The equations originate from the central projection of a point of the object through the optical centre of the camera to the image on the sensor plane.
