(b) Movement trajectory: a well designed movement trajectory can eliminate collinearity (coplanarity) problem and make full use of the real-time information, that is, the distribution of unknown nodes, environment information, and so forth.
Diagnostic tests for collinearity are: VIF (variance inflation factor), correlation matrix of variables, eigenvalues and eigenvectors, condition indices, variance proportions.
It can be seen from (11) that the object-space collinearity error function can be minimized with respect to the rotation matrix A only.
Regression assumptions were checked and met, including testing independent errors (Durbin-Watson statistics = 2.15), collinearity (tolerance values > .82), and linearity and homoscedasticity (P-P plots).

In order to decrease the extent of descriptor interaction, several descriptors must be removed from the model while monitoring the condition index obtained from running a collinearity diagnosis.
The output shows no presence of collinearity. The mean absolute percentage error whose formula is indicated in the formula (2) was calculated in order to test this first regression model.

Moderate collinearity is symptomatic of OLS regression of many variables, and is anticipated especially in the initial model, which simply represents a means to a more parsimonious solution.
