我的目标是找到 、 、 和 之间的相关性UNBALANCE_2
并UNBALANCE_1
进行预测ANGLE_1
,所以我决定使用回归,现在我在为我的模型识别正确的方程时遇到了问题。ANGLE_2
W
我做了什么我被使用了nls
,但仍然没有结果
model_nls <- nls(W ~ b1*UNBALANCE_2^2+b2*UNBALANCE_1+b3*ANGLE_1+b4*ANGLE_2,start = list(b1 = 17,b2 = 7, b3 = 0, b4 = 0), data = sub12)
summary(model_nls)
Formula: W ~ b1 * UNBALANCE_2^2 + b2 * UNBALANCE_1 + b3 * ANGLE_1 + b4 *
ANGLE_2

请帮忙弄清楚:
我当然应该
sin
在我的模型中使用函数吗?p
当值表明参数之间的相关性非常弱时,是否有可能做出有价值的预测?至于3个模型残差很高就说明模型定性不对?我应该怎么办 ?
谢谢您的帮助。
