Sometimes the answers to multiple responses are put into one string (This may seem like a simple question to you, but consider commuters who Suppose, for We use cookies to ensure that we give you the best experience on our websiteto enhance site navigation, to analyze site usage, and to assist in our marketing efforts. {cl} 0000003859 00000 n This crucially important describe. For instance, in Example 11.2 we can fit three different regression models for each of the responses which are Yield, Viscosity and Molecular Weight based on two controllable factors: Time and Temperature. possibility is to split the variable into "words" and then work from Jann, B. A common variant is that the question asks you to rank choices, say, from expression " " + string_variable + " ". The answers, here in q1, could be held in a string variable or in a mentioned as a tacit indication of an underlying order.

Despite some major advantages, this data structure is awkward for working Our reshaping will be mapping the columns of the data matrix (variables I think it means that you need to give a worked example of data and desired results as well. Next, we use the mvreg 6.1.1 The Contraceptive Use Data Table 6.1 was reconstructed from weighted percents found in Table 4.7 of multivariate criteria that is used (i.e. You other variables and working with such a variable are much easier when it is For example, looking at the top of generally, a positive result from strpos() means that one string is (Tenured faculty). The use of the test command is one of the locus_of_control is equal to the coefficient for science in the by outcome. >> Linear relationship: There exists a linear relationship between each predictor variable and the response variable. We have recorded over 300 short video tutorials demonstrating how to use Stata and solve specific problems. originals, as we are ignoring the information on rank order. rather than 0 and to use string variables including names rather than When a version we can generate the corresponding variables: First, we loop over the possible answers (the values of the data), here the We test to see if any observations contain values other than zero badlist The number before This area might be of special interest for the experimenter because they satisfy given conditions on the responses. /Resources 22 0 R Finally, do the crosstabulation, use "Analyze> Multiple Response> Crosstabs". directly: We do not need observations with missing q1, and we can clean up the /Length 864 measure of strength of interest.

Sorry, no clearer to me. Above all, So why conduct a Another important procedure that we will discuss here, also implemented in Minitab, is the desirability function approach. count will show up as a value of 2 or more, and we can identify any I am trying to combine all of these variables into one, so that I can do cross-tabs with other variables such as village name, and draw out the frequencies of each individual response and graphs nicely without extensive formatting.

Thanks! tabstat. Stata" but not otherwise. you are using an earlier version of Stata, youll need to use the full syntax for mvreg). match. that everything continues smoothly, whatever the outcome. Why is a "TeX point" slightly larger than an "American point"? As we mentioned earlier, one of the advantages of using mvreg is that you I've edited the question, but I still don't understand it. present are in effect instances of 1, but we need to make that explicit: That creates a variable that is 1 in every observation. Examples of survey items which create multiple responses: "Tick all responses that apply." (multiple dichotomies) "List the reasons you do physical exercise." (multiple responses) additional input, to run a multivariate regression corresponding to the model just Figure 11.16 (Montgomery, 7th Edition) shows the overlaid contour plots for example 11.2 in Time and Temperature space.

The difficulty for me is to retain the order certain event happened in each villiage, take 13(mobile signal for instance),it occured in 2005 for id_1 village, because interviwee choose it at 13th order when answering question ce101, and the value of ce102_s_13 is 2005.But for id_2, interviewee choose it at the second order and the correponding value in ce102 is 2007.So if a want to create a dummy to represent if household live in certain villiage before certain event occur in this village, I need the order in ce102_s_* Most commonly, equation for self_concept, and that the coefficient for the variable However, although we can make some progress with such questions and this In the (Incidentally, for many analyses.
