<P> However , in casual use , the word `` implies '' loosely means suggests rather than requires . The idea that correlation and causation are connected is certainly true ; where there is causation , there is a likely correlation . Indeed , correlation is used when inferring causation ; the important point is that such inferences are made after correlations are confirmed as real and all causational relationship are systematically explored using large enough data sets . </P>
when does correlation allow you to infer causation
after correlations are confirmed as real and all causational relationship are systematically explored using large enough data sets
