Quadratic Curve Parameter Estimating Method on Sequential Data of Small Samples
Guokai Wu · Hubei Nongxueyuan xuebao · 2002
A new way of fitting quadratic curve y t=a+bt+ct 2 and a specific estimating formula of three parameters which is very simple with little error and suitable for incomplete sample set were put forward.A practical example with the method showed that the fitting result is superior to other ways.
