Definitions:

Multicollinearity

A situation in statistical modeling where two or more predictors are highly correlated, making it difficult to discern their individual effects on the dependent variable.

Regression Coefficients

Values that represent the relationship between a dependent variable and one or more independent variables in regression analysis.

Standard Errors

A measure of the sampling variability of an estimate.

Multicollinearity

A statistical phenomenon where two or more predictor variables in a multiple regression model are highly correlated, leading to difficulties in determining the individual effect of each predictor.
