I have Y vectors = (0, 5, 10, 15, 20)

At Condition1, x Vectors = (-0.0056, 5.0000, 10.0057, 15.0057, 20.0000)

At Condition2, x vectors = (-0.0028, 5.0028, 10.0085, 15.0085, 20.0028)

At Condition3, x vectors = ( 0.0000, 5.0056, 10.0113, 15.0113, 20.0056)

There can happen many conditions between condition1 and condition2 or between condition2 and condition3.

I calculated the co-efficients for conditon2.

When I apply x = 10.0057 for condition1, I get y = 9.99720

When I apply x = 10.0085 for condition2, I get y = 10.0000

When I apply x = 10.0113 for condition3, I get y = 10.002798

To get y = 10.0000 for any condition, Do I have to calculate co-efficients individually? Or is there any mathematical model?

Thanks in advance.
