Dr Packard's model gets round this by abandoning simple logarithmic transformation in favour of a more complicated, so-called nonlinearmodel.
通过舍弃简单的对数转换进而采用更复杂的非线性模型,帕卡德博士的模型解决了这个问题。

The method is used when the model is complex and nonlinear (that is, parameters do not co-vary in a linear manner), or when the model involves more than just two or three uncertain parameters.
