However, I don't have a unique 'j' variable each record in the long-format file has several key variables. Transpose the data into wide format: reshape wide y, i (idc year) j (ida) 7. Delete a column with Accounts, but keep ida (ID for Accounts): drop Accounts. Other users who have found the question cross-posted are encouraged to share the links as a reply as well.This content has been archived, and is no longer maintained by Indiana University. So here's my trouble: I'd like to reshape a long-format data file to wide. dcast () function in R gets the table name and the list of columns to be kept constant (countries) and list of columns to be reshaped (variable) is passed as argument in order to reshape from long to wide as shown below. Transpose data into long format: reshape long y, i (idc ida) j (year) 5. If you've asked a question, let people know where else you asked the question and what your solution(s) were!

#RESHAPE LONG STATA HOW TO#
See the sticked "READ ME: How to best ask for help in /r/Stata" post on how to comment here if all else fails. Make sure to include the word "Stata" in your search query. Perform a web search for your question prior to posting here. The following example data contains two participants measured on two outcome variables (weight and calories), under three different time points. This post shows you how to change from long data to wide data that is, from a stacked. Stata's online community has been active for many years and many questions and solutions are documented on StataList, which are highly indexed on contemporary search engines (e.g., Google). Investigate Duplicates in the Data (1a.) If you suspect that duplicates exist in your data, as in this example You can use duplicates report to investigate Most observations are unique. The Stata reshape command can convert the data files between these two formats. Downloading data from a platform like WRDS can give you the data you need but not in the layout you desire. Hence, taking a dataset from long to wide and back to long will result in getting the same dataset labelling back again. Stata requires the variables over which we perform the reshape command to be num-bers rather than string.
We are starting with the worksheet Initial Download. Stata has extensive and complete documentation you can read before posting here (and you can type help followed by the command name in console to see it, e.g. Downloadable reshape8 improves reshape by preserving variable labels as much as possible when switching back and forth between long and wide dataset formats. Each worksheet in the accompanying Excel le (Sample-Data.xls) matches up with each of the steps below. This is not a place to find Stata tutoring. Then we write the name of the variables we want to reshape, but only the 'stem' - not the time. First we write reshape long to indicate that we want to create a long dataset. The reshape command from wide to long The command is very similar to what we did previously, but not entirely. Do not request that the /r/Stata community do your homework for you. Siffrorna mste vara p slutet fr att Stata ska fatta. For example: reshape long z250 z500 z1k z2k z4k z8k, i(PTID) j(Ear L R) How do I do the rest I can't enter multiple j(new variable) as it only allows me to create one new variable. Assume good faith questions and comments. I have tried using the reshape function but can successfully only creat one variable such as Left or Right ear. Reshaping is a very computationally intensive command. To convert between wide and long data, Stata uses the reshape command.
