Advance your data science understanding with our free tutorials. Use Stata value labels to create factors? (version 6.0 or later). # convert.underscore. Convert "_" in Stata variable names to "." in R names? # warn.missing.labels. Warn if a variable is specified with value labels and those value labels are not present in the file. Data to Stata write.dta(mydata, file = "test.dta") # Direct export to Stata So this command creates a new variable time that has a ... tsset time; Let STATA know that the variable time is the variable you want to indicate the time scale. 14-23 Example: AR(1) model of inflation – STATA, ctd. . gen lcpi = log (cpi); variable cpi is already in memory . gen inf = 400*(lcpi[_n]-lcpi[_n-1]); quarterly rate of inflation at an annual rate This creates a new variable, inf ... In this article I will show how to use R to perform a Support Vector Regression. We will first do a simple linear regression, then move to the Support Vector Regression so that you can see how the two behave with the same data. Previously, we described how to perform correlation test between two variables.In this article, you’ll learn how to compute a correlation matrix, which is used to investigate the dependence between multiple variables at the same time.The result is a table containing the correlation coefficients between each variable and the others. Below we use the logit command to estimate a logistic regression model. The i. before rank indicates that rank is a factor variable (i.e., categorical variable), and that it should be included in the model as a series of indicator variables. Note that this syntax was introduced in Stata 11. logit admit gre gpa i.rank Iteration 0: log likelihood = -249.98826 Iteration 1: log likelihood = -229 ...
