how to make age insignificant why are all coefficients insignificant? why do coefficients become insignificant does age become insignificant a regression variable of age when you add age and age in regression what is the result? what makes the coefficient of age more insignificant when adding a dependent variable in cross sectional regression, the coefficients become insignificant. when do coefficients change in a cross sectional regression? when adding age the coefficients are very small if you add age, age, and age in your regression, the coefficients become very small and insignificant a coefficient becomes insignificant when you add age as a variable age and age become insignificant when adding additional variable does age play a part in the regression when i add age and age in the regression, my coefficients are highly important but they become insignificant. age is insignificant which variables make a regression insignificant what is the coefficient of age when compared to age when age is added to a regression, it becomes more significant and more insignificant. when does age become insignificant are coefficients statistically significant
