PS:

My formatting for the example table messed up.

Here is the table I would like to generate:

                   Foreign Car    Domestic Car     No Car
Price $40,000      %                %              %

> Hello,

> I have a question regarding generating tables of baseline characteristics for publication (whether I should breakdown results by outcomes, or by predictors).

> BACKGROUND:
>
> Suppose I have the outcomes Foreign Car, Domestic Car, and No Car.
>
> I also have the predictor variables Price $40,000.
>
> I would then want to generate the following table:
> Foreign Domestic No Car
> Price $40,000
>
> Now, I have 2 options:
> 1. I can use -by(outcomes), sort: ci price40-, which will give me the breakdown of price within each outcome. In this case, the percentages within each group add to 100%.
> 2. I can use -by(price), sort: ci foreign domestic nocar-, which will give me the breakdown of price across each outcome, thus allowing me to compare differences between each outcome. In this case, the percentages across groups add to 100%.
>
> QUESTION 1:
> Is there a better way to do option 2? If I do it the way stated above, I would have to run that command for each of my predictor variables, which is cumbersome.
>
> QUESTION 2:
> In what scenarios would each of the 2 methods for breaking-down-the-population be used best? Do they each have their place, or is one preferred over the other?
