string variable stata

When dealing with string variables in Stata, blanks spaces can make it difficult to identify values. Subsequently you may use the variables in r (varlist) to recode the variables you want to recode. In a case where your string variables are in fact strings (e.g., "female" instead of "1") you have to tell Stata to encode [varname] the string data. In any numeric variable 6==06 and so 06==6. Found inside – Page 13-18If the outcome variable is mode of transportation (e.g., walk, bike, transit, auto), the relevant ... This means that Stata treats them as string variables. From the first row of observations. Let us go through step by step. Among these string functions are three functions that are related to regular expressions, regexm for matching, regexr for replacing and regexs for subexpressions. In the following table, the first column shows different date formats in which the date is already recorded and brought into Stata. The date variable is not a number. The destring command.

With regard to our test data, the syntax below shows how to convert numeric_1 into (previously created) string_3. This is part four of Data Wrangling in Stata. 21 Jul 2019, 03:10. Let’s destring it: foreach var of varlist _all { local vartype: type `var' if substr ("`vartype'",1,3)=="str" { replace `var'=ustrlower (`var') } } 1. You should type keep if facility=="bir" That way, Stata knows that "bir" is a string value. For dates before 01 Jan 1960, Stata assigns negative numbers as the number of elapsed days. To convert them into a Stata date, the example code is shown in the second column. In any numeric variable 6==06 and so 06==6. I had a big dataset on prescriptions in patients in wide STATA format: 1 observation per patient with several hundreds variables. For instance, foreign in Stata's auto dataset is an indicator variable: 1 if the car is foreign made and 0 if domestic made. Using -labgen-, -labgen2-, or -genl-. The first line of code converts the numeric variable to string variable. Stata variables are all associated with a display format.

The first theoretical part of the volume is providing the econometric foundations to deal with these new high-dimensional panel data sets. One method of converting numbers stored as strings into numerical variables is to use a string function called real that translates numeric values stored as strings into numeric values Stata can recognize as such. In this book, author Kyle Longest teaches the language of Stata from an intuitive perspective, furthering students’ overall retention and allowing a student with no experience in statistical software to work with data in a very short ... String processing is fairly easy in Stata because of the many built-in string functions. that inequalities can be resolved for string arguments as well as for numeric arguments, and equally that cond() will readily produce string results if instructed. Data Wrangling in Stata: Variable Transformations. One example: When I use functions: -regexm-, -strpos- or -strmatch- and I am searching for "INC" only Stata return all observation that contain "INC" like INCOME or something else, but I need only observations with "INC" The person < twin string for Stata means that the value of person is less than the value of twin. Demonstrating the use of strategies and tools for documentation, they provide robust examples and offer the datasets for download online.

Converting dates entered as strings into numeric dates that can be used by Stata is relatively simple. 2 A string variable when sorted is necessarily in alphabetic order, or more generally the order given by the string characters used. The encode command turns categorical string variables into encoded numeric variables, while its counterpart decode reverses this operation. Stata allows the labeling of variables and also the individual values of categorical or ordinal variable values. If you type keep if facility==bir then Stata will look for a string variable named bir, and will complain if it doesn't find it. While the syntax for transforming variables in Stata is simple, the process of converting an idea for how to change a variable into actual code can take some getting used to. This is necessary as the date function can work only on string variables. It creates a new string variable that gets its variable values from the previous label values. When I add the variable to the dataset, STATA recognizes it as a string variable. In that case, you should find out the numeric value labeled as "Germany" – cap.py Jul 1 '20 at 6:18 Float and string variables are some of the variables that express or shows information in a well understandable manner. substr works for string variables. 11 Jul 2018, 23:30.

The "tricks and shortcuts" mentioned were introduced with Stata 12.0. The YMD is called a mask, and it tells Stata the order in which the parts of the date are specified. Even though Stata can handle string variables, it is clear in many … If you map to a numeric variable, you can use value label definitions to insist on a different order. All date functions takes two arguments: the name of the string variable and a string specifying the order of the date and time components called mask. FLOAT VARIABLES AND STRING VARIABLES IN STATA STATISTICAL APPLICATION A dataset is the gathering or collection of different types of information called the variables, which are mostly organized or arranged by columns. This timely, thoughtful book provides a clear introduction to using panel data in research. Before we can use the Stata time-series or panel-data capabilities, we need to convert the string date to a Stata date. Thus suppose that you create new variables, for example,. To our end, we can use function dofm (). Combining strings into one variable Posted on November 24, 2020 by Jan Sauermann I’m again playing around with strings in Stata and need to combine (string) variables with (string) variables as well as strings in locals with string variables.

In order to replace “make”, we will use the command: destring make, replace : where oldvar is the name of the old variable and newvar is the name of the new variable. See the help for encode and label. Thus suppose that you create new variables, for example,. In the above code block, we loaded the first dataset i.e. Stata has many tools for working with dates. sysuse auto . In that case, Stata will split the data set up into one group for each unique combination of the variables. You can then use that number in a variety of ways. It will work with all of the variables you show, except date. But note that as of version 13.0, Stata offers two types of string variables: "Short" string variables with up to 2045 characters.
