Hi,

I need to calculate forecast or trend analysis FOR COLUMN 'PAID', on datasets with more than 2 columns like:

Date	Gender	Age	Product	Color	PAID
01/02/2012	M	30	X	BLUE	YES
01/02/2012	M	35	X	BLUE	YES
01/02/2012	F	28	X	BLUE	NO
02/02/2012	M	42	X	RED	NO
02/02/2012	F	27	Y	BLACK	NO
02/02/2012	M	19	Y	BLUE	YES
02/02/2012	F	12	X	BLUE	NO

Thank you
