9 Jun 2003 The manual doesn't say this explicitly but the rule "find the smallest index i such that i > P where P = N*(p/100)" ensures that percentiles fits this definition. Hence, it would seems that the commands consider percentile ranks as values that fall within the intervals: interval (p^th perc. rank) corresponds to
your way (kind of) egen mpg4 = xtile(mpg), nq(4) gen lowq = mpg4 == 1 gen highq = mpg4 == 4 *----- // what you want summarize mpg, detail gen lowq2 = mpg < r(p25) gen highq2 = mpg < r(p75) *----- summarize high* low* list. Now check the listing to see what's going on. See help stored results .
xtile creates a new variable that categorizes exp by its quantiles. If the cutpoints(varname) option is specified, it categorizes exp using the values of varname as category cutpoints. For example, varname might contain percentiles of another variable, generated by pctile. pctile is a programmer's command that computes up to
11 Mar 2010 If the expenditure variable is 'exp' and 'weight' is the weighting variable, then to create the income quintiles type xtile quintile="exp"[aw=weight], n(5) you can use the 'if' command if necessary. i.e xtile quintile="exp"[aw=weight] if------, n(5) 2. you can tabulate your expenditure vairable by the income quintiles. if
25 Oct 2012 Hi Nick, Thanks for your help, I really appreciate it and would definitely give it a try. And yes indeed it is Indonesia! I guess the '33 provinces' gave it away, eh?

Hello, I am trying to generate an income quantile variable using xtile. For some reason, the new variable has less levels with This is most likely correct behaviour due to all of the zeroes. See the technical note in the PDF documentation for xtile, eg page 8 of www.stata.com/manuals13/dpctile.pdf
may be specified and are separated by white space, such as statistics(mean sd). Available statistics are statname. Definition statname Definition mean mean p1. 1st percentile count count of nonmissing observations p5. 5th percentile n same as count p10. 10th percentile sum sum p25. 25th percentile max maximum median.
iqreg estimates interquantile range regressions, regressions of the difference in quantiles. The estimated variance–covariance matrix of the estimators (VCE) is obtained via bootstrapping. sqreg estimates simultaneous-quantile regression. It produces the same coefficients as qreg for each quantile. Reported standard errors
We changed the pattern of the reference line by specifying rlopts(clpattern(dash)). In a quantile plot, each value of the variable is plotted against the fraction of the data that have values less than that fraction. The diagonal line is a reference line. If automobile prices were rectangularly distributed, all the data would be plotted
