Hi, Here I have a query for finding the ratio of the variables.

The data looks like

a b c d 2 . 5 7

Now I'm able to find the ratio of non missing variables, i.e., a:c:d=2:5:7

But I require the missing variable too to be included in the ratio.

i.e., The ratio required is to be in the form a:b:c:d=2: . : 5 : 7

Could anybody suggest anything for this?

Thanks, Shashi
