Hey,
Im trying to use a lookup function to find multiple dates and their
corresponding metal loss value in amongst a huge sheet of data. These
dates (col. A) and the numbers I am after (Col. B) are taken at
irregular intervals and I need to find a way of looking up how many
dates occur during a certain period and more importantly, a regression
line on the numbers in col. B.
I can do a regression line on the numbers using linest, but I dont want
to have to manually select the range each time.
Any ideas?
Cheers...
