Hi everyone,

in the first question, "how much possibility could you use the car of your household when you plan to go to a leisure activity, such as watching a movie, go to sports?" and the answers include 20%, 50%, and 80%. THEN, in the second question, I want to generate a 0-1 variable by the possibility got from the first question. Does anyone know whether it is possible to achieve it? Thanks for help in advance.

Best,

Which type of question do you want to use for this 0-1?
Please give an example 

The question seem to be "What is the probability in percent that you use your household's car for a leisure activity (e.g. to watch a movie or go to sports)??"
Are there more than these three ( 20%, 50%, and 80%) answer items? What about 0% and 100%?

What is the purpose of the dichotomous (0,1) variable?

Still rather clueless.
But a built in way to get  dichotomous variables out of a single punched question is:

Use a multiple question.
In the export settings there is the option to change the "Y", "" to whatever character you like.

Otherwise you have to use some equations, like
eq20: {if(Q1=="20",1,0)}
eq50: {if(Q1=="50",1,0)}
...

Or you set a hidden multiple question by equation. Result the same as above. In the export you select your desired values
Like
{M1_1={if(Q1=="20","Y","")}
{M1_2={if(Q1=="50","Y","")}
​​​​​​​...

Or you use a hidden question (multiple numbers) by equation.
Like
{M1_1={if(Q1=="20",1,0)}
{M1_2={if(Q1=="50",1,0)}
​​​​​​​...

As you see, there are several options.

So, please explain.
(As we are not part of your TUE group who deals with the new ideas of public transportation, we have no idea what you want to achieve  ) 

Like Jelo, find the question rather strange and I would guess that there is a very high probability that a family car will be used 100% for leisure activities for most respondents. Who has their family car just for work or chores?

Hi Joffm,

Sorry for the late response. Thanks for your help. I think your methods are useful for me. I want to explore which transport respondent prefer to choose under some uncertain purposes. in fact, the private mode may be occupied by others in your household and the alternative should not be shown. This is why I want to make the alternative of Private car appear with a possibility.

Hi Holch,

I want to set a possibility of car availability in normal. because it is possible that others in your household need to use it. For example, for the purpose of going shopping, statistically, you could use private car 6 times in 10 times and the other 4 time you could not use it, because others need it.

I don't understand anything in context. What does "the private mode may be occupied by others"?    I understand that you want to display/hide answer items with a certain probability. 20%, 50%, and 80% where not answers, but probabilities.

You better create a survey with a few questions and attach the LSS-export here. That might help to understand the complete context and the question types used.
 

Hi jelo,

the purpose of dichotomous (0,1) is to do statistic. under a certain purpose, what percentage is the private car is available for you?

Qiang

Yes, of course.

But till now you did not provide an example.
How does the first question look like?
How is it to be transformed to your dichotomes?

Please, explain.

Hi joffm,

In fact, I have not done it. It is an idea until now. I will do it a.s.s.p and show here.

But you certainly can show how the first question looks like.
Is it a single punch question with answer options  "20%", "50%", "80%"?
Or is it a multiple numeric question where the repondent enters probabilities?

And how do you want to store the dichotomous results?
Multiple question with subquestions "20%", "50%", "80%"?
Several single questions with answer options "0" and "1"?
Array with subquestions "20%", "50%", "80%" and answer options "0" and "1"?

So, if a respondent selects "20%" in the first question, what has to be stored in the second?
You could even store a simple string like "010" or "001" in a text question (or comma separated ("0,1,0")

Everything possible and easy, but ou have to tell us.
