Xtile stata how to#
Unlike Stata's official xtile, astile is byable. Completely lost with how to split my data into quintiles. It's speed efficiency matters more in larger data sets or when the quantile categories are created multiple times, e.g, we might want to create portfolios in each year or each month. astile is faster than Stata official xtile. For example, if we want to make 10 portfolios, values of the newvar will range from 1 to 10. up to n, where n is the maximum number of quantile groups specified in the nq option.
For example, the difference in time when used with bys and without bys is usually few seconds in a million observations and 1000 groups. astile handles group-wise calculations super efficiently. Values of the newvar ranges from 1, 2, 3. Unlike Stata’s official xtile, astile is byable. astile creates a new variable as specified in the newvar option from the existing variable which is specified in the = exp. This will involve placing the smallest 10% firms in portfolio 1, next 10% in portfolio 2, and so on. For example, we might be interested in making 10 size-based portfolios.
