WebTo plot marginal effects of regression models, at least one model term needs to be specified for which the effects are computed. It is also possible to compute marginal effects for model terms, grouped by the levels of another model’s predictor. WebIf we remove the atmeans option we get the average marginal effect, i.e., the discrete change in probability for each of the values of s averaged across the observed values of m. Here is how the margins command looks now.

However, I was also taught that given an x such as 10, one can simply insert 10 in the equation, so that y hat when x is 10 is -0.0104 (10) + (-0.00002) (100). Doing so, I get -0.106. diy hermit crab
