Compute geodist for each row stata4/13/2023 Since Death = 1, we can sum up the total Deaths a patient experiences and drop those values that are greater than 1-because a patient can only die once. We can do this using the bysort command and summing the values of Death. This is a handy way to make sure that your ordering involves multiple variables, but Stata will only perform the command on the first set of variables.įirst, we want to make sure we eliminate the repeated deaths from Patient 8. Stata orders the data according to varlist1 and varlist2, but the stata_cmd only acts upon the values in varlist1. The bysort command has the following syntax: bysort varlist1 (varlist2): stata_cmd Removing the patient will result in a loss of information for Site B, but keeping the patient complicates the panel data when we convert from wide to long format. There are two ways to approach this: (1) remove the patient from Site B or (2) keep the patient by distinguishing it at each sight. The highlighted boxes indicate a patient was observed at two different sites. For instance, in Month 1, there were 5 observations. For each month, there are different numbers of observations. ![]() In this example, we have a data set with time (months) in the column and patients in the rows (this is called a wide format data set). You can download the sample data and Stata code at the following links: However, when it comes to panel data where you may have to distinguish a patient located at two different sites or a patient with multiple events (e.g., deaths), it’s important to organize the data properly. For example, sorting by the time for time series analysis requires you to use the sort or bysort command to ensure that the panel is ordered correctly. When using SSL, use the URL option to pass in theĭatabase.Sorting information in panel data is crucial for time series analysis.
