Regression analysis often treats category membership with one or more quantitative dummy variables.
The dummy variable models can easily accommodate discrete characteristic spaces.
Since trees can handle qualitative predictors,there is no need to create dummy variables.

To distinguish between claimants providing numerical data andthose who did not, a dummy variable was created taking a value of 1 if the value was missing.
The dummy variable models(32) and(34) are completely nonparametric and hence are much more flexible than traditional flexible functional forms.
In order to observe the influence of changes of independent variables on changes of dependent variables, the data, except the Dummy variable, were used in log(e) form.
Some studies include a dummy variable for heat waves in models[15]while others adjust for continuous temperature besides a dummy variable 16.
The variables included Brent price, an equity index of six large oil and gas companies and several dummy variables to reflect possible structural changes.
In this study, we used a dummy variable to represent the 2011 heat wave and then estimated the cumulative effects of the 2011 heat wave by considering its lag effects using DLNMs.

Two dummy variables associated with the“high” and“low” groups of outlets also appear in this model, namely Outlet-High and Outlet-Low, so the intercept corresponds to“medium” outlets.
Different investigators will choose differingnumbers of classification cells; i.e., differing dummy variable hedonic specifications made by different hedonic operators will choose differing I's and J's, leading to a lack of reproducibility in the models.
