SAS data manipulations
SAS Transpose : “So many times we need to take our data and turn it around. One of the reasons that this is done is that it
is more efficient to store your data in a vertical format and processing the data is easier in a horizontal
- Changes the variables (columns) into observations (rows)
- eliminates the need to write a complex data step
- Horizontal data has many variables with few rows. There will be empty cells in the data if there are any missing values
SAS Summary/SAS Means : In SAS, you can use the
SUMMARY procedure to obtain summary statistics such as the median, skewness, and kurtosis
By definition, a median is a statistical term identifying a piece of data (number) that divides numerically ordered data into two equal halves. In easier terms, the median is the middle piece of data when those data are placed in numerical order.
