请问一句话用英文写

These studies were slanted to qualitative analyses,
but either lack more quantitative analyses or adopt
not quite precise model.
原意：这些研究倾向于作定性分析，而缺少定量的分析或采用不太精确的模型
上述英文这样写可以吗？
还是有更好的写法？
谢谢

slanted to 不太好，chinglish

These studies tended to use qualitative analyses, few of them adopting quantitative analyses or precise model.
