Today when I read the esttab command of Stata (http://repec.org/bocode/e/estout/hlp_esttab.html), I saw the star options
Array


I know how to convert it to * for p<0.1, ** for p<0.05, *** for p<0.01 (the commonly-used p-value to set the levels of significance). But I am wondering why Stata set the default like that, is there anything important that I missed?
