The collapse command in Stata is used to create summary variables from an existing dataset. It allows you to aggregate observations within groups, summarizing them into a new dataset. Collapsing a dataset can be useful for creating summary statistics, such as the mean and standard deviation, for ...

I see no need to create a set of new variables; that will only waste space, which seems to be scarce in this particular problem. Instead, just form a new varlist that consists of only those that are actual variables (and not completely missing). Thus it is a subset of varlist1. Her...

Like all programming languages, Captivate Classic uses variables to temporarily store values, which can be used by other components of Captivate Classic. In Captivate Classic, there are two types of variables, system and user-defined. System variable: System variables come pre-defined with your ...
Assumption #3: You should have independence of observations (i.e., independence of residuals), which you can check in Stata using the Durbin-Watson statistic. Assumption #4: There needs to be a linear relationship between (a) the dependent variable and each of your independent variables, and...
A binomial logistic regression is used to predict a dichotomous dependent variable based on one or more continuous or nominal independent variables. It is the most common type of logistic regression and is often simply referred to as logistic regression. In Stata they refer to binary outcomes when...
In R, how do I code "only show the first 2 words" of an output? Seeking help for using filter and mutate command to break down a current variable into separate variables Rstudio crashs on macOS with the X11 cairo type window Principal Components Analysis (PCA) Error: Long vecto...
Dear STATA users, I wonder how I can compare the values of a variable, say var1, at different observations? (In particular I want to do regressions such as the one below) if var1(at line 2) = var1(at line 10 ) { regress y x in 2/10 } Thanks for suggestions, Sarah On 7/18...
but the problem is i don't now the min and max values. I want to drop the observations if they are under 2.5% and over 97.5% of the maximum earnings. Boris This would have been useful to state in your original question! Its not that hard though... ...
