After several initial meetings discussing such things as necrotizing enterocolitis (NEC), retinopathy of prematurity (ROP), patent ductus arteriosis (PDA), and
SAS University Edition has been available for free download for six months – in that time we’ve seen 50,192,670 PROCs or DATA steps executed globally – that’s almost 4,000 hours duration! Now, we were founded on stats so we thought we’d bring you some of the key metrics we’ve discovered over
