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).
According to data obtained from the NFL by Darren Rovell of ESPN, the NFL takes a 25% royalty from the wholesale price (1/2 retail), donates 90% of royalty to American Cancer Society.. In other words, for every $100 in pink merchandise sold, $12.50 goes to the NFL.Of that, $11.25 goes to the American Cancer Society (ACS) and the NFL keeps the rest.The remaining money is then divided up by the company that makes the merchandise (37.5%) and the company that sells the merchandise (50.0%), which is often the NFL and the individual teams.Then consider that only 71.2% of money the ACS receives goes towards research and cancer programs.he remaining money is then divided up by the company that makes the merchandise (37.5%) and the company that sells the merchandise (50.0%), which is often the NFL and the individual teams.
