The model has three variables X, Y and Z, where Z=Y/X. The linear
correlations among X, Y and Z are low. Is this model OK? Any comments are
highly appreciated!

George Box said: All models are wrong, but some are useful. The model is
okay, but It depends on how to use it.

For created variable such as Y/X, it is fine to include it into the model
once it makes sense in business, or in the field the model will be applied
to.
在俺与这么多clients打交道的过程中,这种变量组合如果能很好的从business角度解
释的话,是最受欢迎的。
如果variable不make sense,就算在线性,再significant,也不能用。
