Hi all, I have got a dataset. In Excel, I can fit a polynomial trend line beautifully. However, the equation that Excel calculates appear to be incorrect. So I am thinking about using R.
My questions are: (1) How do I fit a polynomial trendline to a graph? (2) How do I calculate and display the equation for that trendline? Many thanks for your help. Greatly appreciated.
