Abstract

Prognostic model building is a process that begins much earlier than data analysis and ends later than when a model is reached. It requires careful delineation of a clinical question, methodical planning of the approach and attentive exploration of the data before attempting model building. Once following these important initial steps, the researcher may postulate a model to describe the process of interest and build such model. Once built, the model will need to be checked, validated and the exercise may take the researcher back a few steps - for instance, to adapt the model to fit a variable that displays a ‘curved’ pattern - to then return to check and validate the model again. To interpret and report the results it is vital to relate the output to the original question, to be transparent in the methodology followed and to understand the limitations of the data and the approach.

预后模型:统计学家希望临床医生了解的内容
预测模型的建立是一个比数据分析更早开始,比模型建立更晚结束的过程。在尝试建立模型之前,它需要对临床问题进行仔细的描述,对方法进行有条不紊的规划,并对数据进行仔细的探索。一旦遵循了这些重要的初始步骤,研究者就可以假设一个模型来描述兴趣的过程并建立这样的模型。一旦建立起来,模型将需要被检查和验证,并且这个练习可能会让研究人员后退几步——例如,调整模型以适应一个显示“弯曲”模式的变量——然后再返回来检查和验证模型。为了解释和报告结果,至关重要的是将输出与原始问题联系起来,在所采用的方法中保持透明,并了解数据和方法的局限性。
