Hi everyone,
I'm preparing for the SAS Certified Data Scientist Exam (A00-250) and could use some help with the following topics:
1. Data Manipulation
Best methods for handling missing data in SAS?
How do you merge datasets with mismatched keys or inconsistent formats?
What’s the best way to transform variables for machine learning models?
2. Predictive Modeling
How do you assess model performance in SAS (e.g., cross-validation, ROC, confusion matrix)?
When would you choose decision trees over random forests?
3. Machine Learning
How do you implement k-means clustering in SAS?
What's the difference between SVM and logistic regression, and when to use each?
I'm hoping this certification will help me advance my career, but if you think there’s a better certification path, feel free to suggest one!
Any resources or tips to help with these areas would be greatly appreciated! Thanks in advance!
Which site can help me? One of my Friend Suggest me the certstime will help me in that case, but i am not sure so me if any only of you can know any thing about thing, Please Guide me.
