from a dataset take 90% into one dataset and 10% into another dataset

Question

Accepted Answer

Split a dataset into two datasets with 90% and 10% of the data respectively.

Use the SAS DATA step to read the original dataset and create two new datasets.
Use the OBS statement with the POINT= option to specify the percentage of data to include in each dataset.
Calculate the number of observations for 90% and 10% based on the total number of observations in the original dataset.
Example: data dataset1; set original_dataset(obs=90); run; data dataset2; set original_dataset(firstobs=91); run;
