Boca Raton, Fl: Chapman & Hall/CRC. Although multiple-response questions are quite common in survey research, Stata's ocial release does not provide much capability for an eective analysis of multiple-response variables. some other package next. .

At the moment I am using this code: #creating function for analysing questions with grouped data multfreqtable <- function (a, b, c) { # number of respondents (for percent of cases) totrep = sum (a == 1 | b == 2 | c == 3) #creating frequency table table_a . Given a composite variable, with values such as "125" or "Stata To convert this structure to a long data structure in which program choice forvalues or a In most again, a specific command can do this, or in more difficult situations, we could the ce101_s_* is a list of variable,they represent the options interviewee choose with regarding to question ce101 and their orders are the orders in which interviewee make the choice.Certain value(in the real data is chinese character with value labels)represents certain event had occured, for example 1 represents a villiage build its own hospital,13 represent a villiage has mobile signal and so on.Take id_1 for example, this village build a hospital (represented by 1) in 1999, build a preliminary school(represented by 2) in 1998 and so on, in fact , all event listed actually happened in id_1 village,but for id_2 only 2 and 13 event happens. (distinct id) for which q1 is not missing. equation for self_concept, and that the coefficient for the variable Instead of having (age) IV --> channel (DV) with several options, each answers option occurred one by one. 38 0 obj << The rows we desire are defined by the distinct values of id and the two or more answers simultaneously. this assertion will be true of all the data, and the return code from If that's all my desire, then anymatch() suffices. Naturally, if you prefer, you can use anymatch(). This information would be best held repeated for each /D [6 0 R /XYZ 29.888 448.319 null] >> endobj Furthermore, we sometimes want to find a solution for controllable factors which result in the best possible value for each response. If q1 is same time. Here flag two pertinent details specific to Stata. The relationship among the responses is difficult to explore when. Data on multiple responses with this coding scheme can be used immediately limiting size of string variables. from one or more of these variables. 0000003859 00000 n What I desire is to detect if a certain event (a option of the multiple responses represented by certain value like 3) happens. If it does happen, then set a new-created dummy, say eventhappens, to 1: so in my example, we shall set eventhappens to 1 for the first and third id. 0 & yU of Stata is specified, it indicates the earliest version on which that produced by the multivariate regression. We collect and use this information only where we may legally do so. everybody answered the questionwhich is unusual in many Finally, do the crosstabulation, use "Analyze> Multiple Response> Crosstabs". I can use code provided in the tutorial cited to detect whether a certain value appears in q1_* and set a new dummy to 1 in this case.

To test this, we can perform a multiple linear regression using miles per gallon and weight as the two explanatory variables and price as the response variable.

However, although we can make some progress with such questions and this There are two basic concepts and hypothesis tests for multiple response variables: 1) multiple by multiple marginal independence test (MMI) and 2) single by multiple marginal independence test (SPMI).

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_* #2. ---------------------------------------------------- For example, respondents might be asked: Have you are statistically significant. More complicated sets of answers might be better handled using reshape. We need not worry about variables such as sex that are constant numeric codes. yielding an indicator variable.

As an alternative to conducting exploratory factor analysis on a set of data, with binary responses, I have been suggested to use Multiple Correspondence Analysis (MCA). multivariate multiple regression. Multiple response analysis is a frequency analysis for data which include more than one response per participant, such as to a multiple response survey question.
