<p><strong>Please don't guess what the original poster (OP) intended.</strong>  When the meaning is clear but poorly worded, then rewriting should be fine.  The danger lies in making implicit assumptions (of which you might not even be aware) in formulating your original understanding of the question.  Be cautious.</p>

<p><strong>This is what the commenting mechanism is for:</strong> post a comment asking for clarification.  If possible, be specific about what needs clarifying and how that could be done.  Would it help to use grammatical english?  Provide a statistical context?  Explain terminology?  Given some sample data?  Then suggest so.</p>

<p>In some (very rare) cases, when the problems appear to stem from poor skills in communicating in English or mathematics, people will edit more aggressively.  When they do, they also post comments alerting the OP to the changes and asking them to perform a critical review of them.</p>
