How to interpret regression coefficient

Web13 jul. 2024 · The regression output will obtain an estimated coefficient when the researcher analyzes the data using linear regression. This estimated coefficient becomes the core to help interpret the analysis results. From the estimated regression coefficient, it can be continued with the calculation of elasticity. Web21 mrt. 2024 · The interpretation of standardized regression coefficients is non-intuitive compared to their unstandardized versions: For example, a 1 standard deviation unit increase in X will result in β standard deviation units increase in y. A change of 1 standard deviation in X is associated with a change of β standard deviations of Y.
