Subject | st: Log Transformation of Variable |
Date | Sat, 26 Feb 2011 12:04:48 -0500 |
Good Morning, I have a dataset that I would like to transform by multiplying the dependent variables by -log - e, or in other words, the negative logarithm minus its base. Despite searching this forum and the Internet, I have been unable to find any information on how to "tell" Stata to do this. I am able to transform my variable by multiplying it by negative log: generate transformed_dep_variable = -log(dep_variable) However, Stata errors out when I try to communicate -(log+e), because it no longer recognizes log as a function when I type this in: generate transformed_dep_variable = -(log+e)(dep_variable) Do any long-time Stata users have any suggestions? Thank you in advance for your help!
