Hi,

I want to use least squares method to compared some results with measured data. The only problem is that the points in the data series does not match. So my question is how can I do this?
I though maybe it would be possible to plot the lines and then use least squares on the lines themselves. However I have not been able to get this to work. Next I though about editing the data series to make the points match. As the resolution of the series are quite good, I don't think it will make "too much of a difference". So, does anyone know how to manipulate two data series to match the points on the x-axis by linear interpolation in Excel?

Very greatful for any help I can get
