The elements in x are sorted into 10 equally spaced bins along the x-axis between the minimum and maximum values of x. hist displays bins as rectangles, such that the height of each rectangle indicates the number of elements in the bin. In the previous chapter, we learned how to do ordinary linear regression with Stata, concluding with methods for examining the distribution of our variables. Without verifying that your data have met the assumptions underlying OLS regression, your results may be misleading.

### There is a glitch with Stata's "stem" command for stem-and-leaf plots. "stem" function seems to permanently reorder the data so that they are sorted according to the variable that the stem-and-leaf plot was plotted for. The best way to avoid this problem is to avoid doing any stem-and-leaf plots (do histograms instead). However, if you really

When you use the hist function in Stata, it automatically tells you how many “bins” it used. For example, in the previous examples it always used 8 bins: However, we can specify the exact number of bins by using the bin() command. For example, the following code tells Stata to use 16 bins instead of 8: hist length, percent bin(16) 2016-07-21 · Stata for Students: Histograms.
