There were 4 datasets downloadable (and accessible using the frame on the left.) These data sets are named SALDRU12, SALDRU40, SALDRU60, and SALDRU100. The number after "SALDRU" tells you the rough percentage of the observations that are in each dataset. For example, SALDRU12 contains about 12 percent as many observations as the full data set, SALDRU100.
Memory Requirements by Dataset:
- SALDRU12: 4mb
- SALDRU40: 11mb
- SALDRU60: 17mb
- SALDRU100: 26mb
This is the minimum amount of memory you will need to set aside to use each of the datasets. If your computer has enough memory installed, you can always specify a larger amount of memory.
