WebElasticity--what effect does a proportional change in an arc (vital rate) have on l? For example, if we change first-year survival by 1%, how much will that affect population … WebMar 26, 2016 · You can estimate this model with OLS by simply using natural log values for the variables instead of their original scale. After estimating a log-log model, such as the one in this example, the coefficients can be used to determine the impact of your independent variables (X) on your dependent variable (Y).The coefficients in a log-log model …
