Dear Statalisters, I have a actually quite simple problem, but my STATA (version 7) does not understand me: I want to add 3 variables from a different (using) data set, which has only 1 observation, to my master data set in memory with 28 observations. I tried: merge using var1 ...
How do I s..A standardized variable (sometimes called a z-score or a standard score) is a variable that has bee
Dear Statalisters, I have a simple question. How do I add a suffix to all variables in my dataset. So suppose I want the variables WHEAT, MAIZE, CEREAL to be renamed to FOOD_WHEAT, FOOD_MAIZE, and FOOD_CEREAL. I can't use the command * renpfix * because it only allows you to...
As we dig deeper into Stata or R debate, a few questions have come up.Question 1: One of the things Stata does well is the way it constructs new variables (see example below). How to do this in R? We can rewrite it as-is using for loops in R...
#To print the range of salary packages range.sal <- range(read.data$empsalary) print(range.sal) Output: [1] 20000 36000 #To print the details of a person with the highest salary, we use the subset() function to extract variables and observations max.sal <- subset(read.data, empsalary...
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...
There should be some correlation between variables to make a factor analysis feasible. Types of factor analysis There are two main factor analysis methods: exploratory and confirmatory. Here’s how they are used to add value to your research process. ...
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...

TitleHow to add factor-variable support to a command AuthorTheresa Boswell, StataCorp Question: Why is my command not working with factor-variable syntax and/or collinear variables in Stata 11? Answer: As of Stata 11, variables are no longer dropped because of collinearity. Instead, these varia...
