Which of the following is not a challenge for model specification?
A) Model fishing
B) Finding the appropriate data set
C) Changes in sample size
D) Unclear results due to the use of multiple models

Question

Quizplus · Accepted Answer

Finding the appropriate data set is not necessarily a challenge for model specification, as it is assumed that the necessary data has been collected prior to model development. A) Model fishing refers to the practice of trying out many different models until one provides the desired result, which is a challenge as it can result in overfitting and invalid conclusions. C) Changes in sample size can also be a challenge, as it can affect model accuracy and generalizability. D) Using multiple models can lead to unclear results if they are not well-distinguished or if one model is favored over another without proper justification.
