Opps.. thanx for pointing out Bobby..
Its a typo actually...
I would like to derive the correlation formula between B & C.
(Not A & C)
However, data for A & B is from one set of samples, while B & C is using another set of samples..
Now the only way I could think of is to let C measure the same set of samples that was used for correlation between A & B,
then derive the formula between A & C base on the new measurement data measured by C.
Just wonder is there any other way?

I have a problem here.
Previously I have done a correlation work between two sets of data measuring the same parameter (weight), using two measurement equipments, A & B.
Data from both equipment gives two sets of data, set A & set B.
The formula derived as below:
Y=3.69395X-0.30099

There is another correlation work done between measurement equipment A and another equipment, C;
The formula derived as below:
Y=0.952X+0.0291

Now I need to derive another correlation formula between equipment A & C.
Could someone advise if there is any method I could calculate that?

Thanks in advance!!
