我想问一下大佬用的是什么数学模型

Hi @pxp1230，

Your model for 2019-nCoV looks good, want to learn from, but slightly confusing, so can you help me about these questions?

1. what features you choose within Polynomial Regression.

Only see a text like this:

double result = p[0] + p[1] * x + p[2] * Math.Pow(x, 2) + p[3] * Math.Pow(x, 3) + p[4] * Math.Pow(x, 4) + p[5] * Math.Pow(x, 5);

Can you give me the interpretation of what p[i] are?

-57.7620958751342+178.679492495802*x-44.9790201344528*x*x+2.59980450518181*x*x*x+0.147159013120125*x*x*x*x-0.00389681002953339*x*x*x*x*x

I guess these numbers are the coefficients in the model? how you turn the coefficients?

非常感激感谢如果您能解答！！
