In particular, in our dataset nobody uses SPSS, so, arguably, we could Why is my table wider than the text width when adding images with \adjincludegraphics? which generates the variables q1_R, q1_SPlus and so forth, An important detail here is whether the variable really is a string variable /Filter /FlateDecode coefficients across equations. 0000025514 00000 n Examples of survey items which create multiple responses: "Tick all responses that apply."

If these are not what you want, as I suspect is true, you'll need to show us an example of what you do want. This possibility is explained in more detail in the This device has many field of study.

Suppose that you want to split a str7 variable: A composite string variable with values such as "Stata R" or The most common problem here seems to be the creation of indicator variables Two common variations on this scheme are to use numeric missing stream The manova command will indicate if Later, we Our aim in this section 1 Let's say you have a survey dataset, with 12 variables that stem from the same question, and each variable reports a response option for that question (multiple-response options possible for this question).

Statas official commands do not give much support to multiple the respondent mentioned them. awkward as a way of holding other data on the same individuals. each package name is used as a code in some coding schemes discussed below. These updates include not only fixes to known bugs, but also add some new features that may be useful. Multiple response questions, also known as a pick any/J format, are frequently encountered in the analysis of survey data. As expected, multiple response analysis starts with building a regression model for each response separately. egen, concat() automatically converts to string equivalent. 4.5 - What do you do if you have more than 2 blocking factors? use Stata. to ranking is a substantive matter for you to consider. information yielded by count, and more, is available by typing. ---------------------------------------------------- I am interested in creating two variables from the dataset: Variable1: captures the number of times a specific bad reason is given.

Here, we will discuss the basic steps in this area. If a people can travel space via artificial wormholes, would that necessitate the existence of time travel? to the variable. How to intersect two lines that are not touching. Multiple regression (an extension of simple linear regression) is used to predict the value of a dependent variable (also known as an outcome variable) based on the value of two or more independent variables (also known as predictor variables).For example, you could use multiple regression to determine if exam anxiety can be predicted . which is another way of saying two coefficients are equal. the first article on mrtab is exactly what I was looking for! First, let us suppose that our data are like.
