When you have only one variable, as we do, you can type varname, which is short for varlist(min=1 max=1). Stata will then make sure that your program is called with exactly one name of an existing variable, which will be stored in a local macro called varlist.
Increase in NPV Over Lifetime Due To Steroids To determine the value of using steroids over a playerâ¢s lifetime, we first calculated the increased salary for the player. We used the average length of a Major League Baseball hitterâ¢s career, six years (Schall 2000).This leads to a total increase in salary of $12,512,630. Next we determined the cost of actually buying the steroids. Two different sources put the cost of injectable HGH (high end steroids) at $30,000 per year (Cook 2004). change in the nature and frequency of injuries also pointed to increased steroid use. The number of players on the Disabled List (DL) increased 31%, from 266 in 1989 to 349 in 1998, and the average stay on the DL increased 13% over the same period (Assael 2005).
