which statement is insignificant in terms of standard error what is the difference between a dummy variable and a standard error variable how to find the standard error of regression how is elasticity affected in a spline regression how is beta1 measured in a spline model what is the statistical significance of an estimate for the coefficient of elasticity? which is a statistically significant variable in a piecewise regression model? if a variable has a value that is $3 it becomes spline regression standard error curve when i add an additional variable in the equation, the standard error of the model becomes larger elasticity change in gas price what is the statistical significance of the standard error on the gp log what is the standard error in a spline model of gas prices what type of regression model uses dummy variable what is the standard error for a piecewise logistic regression model? what is the difference between the dummy and independent variable in the piecewise regression model is beta3 statistically significant what is the average standard error value for a piecewise model why is the elasticity of the gas price in the model of spline regression? why is the standard error smaller
