Yes I have, I used macros in creating analysis datasets and tables where it is necessary to make a small change through out the program and where it is necessary to use the code again and again.Īfter I have defined a macro I can invoke it by adding the percent sign prefix to its name like this: % macro name a semicolon is not required when invoking a macro, though adding one generally does no harm.ģ.

Sas interview questions for beginner how to#
know how to use the SAS code node using macro variables My go-to advice for prepping that exam is to read the appendix cases of the course Applied Analytics Using SAS Enterprise Miner.įor someone with more experience you should be able to Any of the questions or general cases seem like fair game for an interview. to explain in simple terms most plots and fit statistics on the model comparison nodeĪfter using EM for a year, you should be able to get the certification predictive modeling using SAS Enterprise Miner. how to interpret the results from the most common modeling nodes how to use decisions and priors for oversampling or train a model with rare events how to avoid overtraining or overfitting a model some best practices like data partition and using imputation only when needed For someone with 1 year experience in Enterprise Miner and data mining, I would expect you to know:
