<p>Some questions, often from new users, pose a practical problem of modeling or forecasting a behaviour of some system and ask for suggestions for modeling or forecasting techniques. In some cases the choice is really very broad, and I start thinking whether the question itself is not too broad (a reason for closing).</p>

<p>However, the question is often specific; there is a concrete problem. But still there are so many possible solutions to be offered.</p>

<p>Should such questions be left intact? Closed? Edits be suggested?</p>
