Whether the prediction has a small enough error margin to be useful is another matter entirely.

而所做预测的误差容限是否足够小，从而使得这个预测还算有用，这完全是另外一码事。

The developmental threshold was fixed at 26 of disease index based on the relative error margin analysis.

根据感病损失量方程，病情很轻时损失甚微，经相对误差限法分析，将病情指数26定为该病的发生指标。

Experimental results show that, comparing with RBF neural prediction method, wavelet neural network prediction method approaches better result, and the error margin is smaller.

实验表明，与rbf神经预测方法相比，小波神经网络预测方法的逼近效果更好、误差更小。
