what is the difference between using function predict() and coef() in prediction
Hi Did you find any difference? The results shall be same (with only rounding error). Can you show us some example where you get substantial difference? Regards Petr
i do not know what is the difference between predict() and coef() i use the two function give me different result zz = predict(xy.lm,list(T8=T8)) ss = coef(xy.lm)[1]+(coef(xy.lm)[2])*T8 where is t8 is the data used in prediction did not use in the fitting in training sample where every sample is 15 value -- View this message in context: http://r.789695.n4.nabble.com/what-is-the- difference-between-using-function-predict-and-coef-in-prediction- tp4173961p4173961.html Sent from the R help mailing list archive at Nabble.com.
