There have been quite a few spam questions over the past few months where it took sometimes days until they got removed.   Proposal Implement an automated process that moves questions from the visible list to some hidden queue for investigation if marked by multiple users an inappropriate content.  To avoid that this process can get misused: Only include users that marked the question if they are not New Users but already on a certain level (to exclude fake users).   And just thinking: Eventually request from New Users for their first few post some additional identification step when posting a question to make it a bit harder to automate posting such questions. ...

  I have a report (e.g. below) where a set of list controls control the data used in the scatter plot and a simple univariate linear regression.    The table below has some reference x values, and the "Predicted" column is derived from the linear regression (right click on object, "Derive predicted", and included as an item in the dataset, avg. aggregation.)    The linear regression itself updates whenever I select/deselect any item in the controls.  But the 'Predicted' values are the values from the initial version of the regression from which I created the field.    Is there any way to get the predicted y values from the regression updating dynamically and displayed in the report below? It should change whenever I change the list control selection.    I just want the report viewer to be able to see the estimated y values at certain x values as they slice data in different combinations.       Thank you! ...

Please  are  there other ways to study or explore in such situations,  thanks. ... View more
