XTILE STATA CODE

(The mean is the middle of a distribution, and the 50th percentile is the sameвЂ¦the middle of the group. If your score was the same as вЂњthe meanвЂќ for that test, you scored in the 50th percentile. mergepoly.ado (with Robert Picard) mergepoly takes a mapping shapefile and merges adjacent polygons by removing shared borders. It has the same syntax and produces identical results, but runs substantially faster in large datasets. If you вЂњscored in the 66th percentileвЂќ, you scored вЂњas well as or better thanвЂќ 66% of the group. fastxtile is a drop-in replacement for Stata's built-in command xtile. T-scores are another type of standardized score, where 50 is average, and about 40 to 60 is usually considered the average range. The command is similar to STATAs xtile command except that xtileJ allows. The average range for a scaled score is 8-10, and 50% of all children at a given age will fall in this range. What does a scaled score mean?ДЄ scaled score is a representation of the total number of correct questions a candidate has answered (raw score) that has been converted onto a consistent and standardized scale. If your raw score is 80 (because you got 80 out of 100 questions correct), that score is adjusted and converted into a scaled score. A scaled score is a raw score that has been adjusted and converted to a standardized scale. Your percent-correct score, which is a type of raw score, is 80%, and your grade is a B.

a stanine of 1 indicating a very low relative achievement. stanine of 9 indicating a very high level of general ability relative to the whole norm reference group, and. What does a Stanine of 9 mean?ДЄ stanine is a score from 1 to 9 with a. For example, if your 9-year-old child scores a 42 raw score on a test, and that score is average for 8-year-olds, their age equivalent score would be 8.

There are much better ways of doing this, but I choose to use the code you have shown us rather than try to improve upon it.Simply put, an age equivalent is a comparison of your childвЂ™s performance compared to age groups whose average scores are in the same range. The following code may give you what you expect - a tab of hospitals by the quintile of the number of patients in the hospital. This package contains R functions corresponding to useful Stata commands. So then your tab is counting the number of patients in the hospitals in each quintile rather than the number of hospitals in each quintile, which would explain why in post #11 the second quintile - whose hospitals are larger than those in the first quintile - has more patients than the first quintile, and so on. Since we know from the code you have shown us that your goal was to calculate quintiles of the number of patients in each hospital, I'd guess that you have - using code you have not shown us - managed to assign to each patient the quintile to which that patient's hospital belongs, rather than just have one observation per hospital with a nonmissing quintile as you show us in post #11. R(r4) = 4Why ist my Quintile 5 so small? What did I do wrong with my code?ДЇrom post #11 I'd say you're using a dataset of 3.7 million observations, which I shall assume represent patients.

quietly replace quint3 = `i' if n_patients < q It has the same syntax and produces identical results, but has been optimized to be. xtile creates a new variable that categorizes exp by its quantiles. fastxtile is a drop in replacement for the built-in Stata program xtile.

quietly replace quint2 = `i' if n_patients <= q xtile Statistics > Summaries, tables, and tests > Summary and descriptive statistics > Create variable of quantiles Description pctile creates a new variable containing the percentiles of exp, where the expression exp is typically just another variable.
