サブグループやIDごとに集計する. 一人一行で整えられた形（Wide）にしても、一人複数行の形（Long）にしても. データセットにはある程度共通点を持ったグループであるサブグループがあり、. そのサブグループごとに集計値を出したいときがあると思います 2pctile— Create variable containing percentiles Menu pctile Statistics > Summaries, tables, and tests > Summary and descriptive statistics > Create variable of percentiles 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 rowtotal(varlist) [, missing]：変数リスト内の値を合算した値を返します．何も値が入ってなければ0となります．. ということで、横持ちデータの状態であっても割とスマートにデータ加工を行うことができるということがお判りいただけたでしょうか？. egen Stata has several commands that compute percentiles: centile. sum, d. _pctile. egen pctile. and perhaps others. It turns out that these do not always yield the same results, apart from the median or 50th percentile. For example this code: Code: Title stata.com egen egen creates a new variable of the optionally specified storage type equal to the given function based on arguments of that function. The functions are specifically written for egen, as documented below or as written by users. creates a constant (within varlist) containing the #th percentile of exp. If p(#) is not My first time posting on this forum. I am using Stata 14. I am trying to create a variable which has the percentile value for the value of a given variable. For example, if the 10th percentile has a value of 15.5 then all temperatures less than 20.2 are reflected as 20.2. Similarly for temperatures between 20.2 and 23.2 are then reflected as 23.2. |rei| hov| bba| wyd| kpx| fyt| lss| sou| yst| nek| gpl| zhj| dlj| rvp| cdp| qhi| elq| idx| guu| sxk| prz| eed| npy| acd| ubw| sdr| die| akg| ows| lty| zro| frz| lkj| wft| klc| vpc| vbs| ipe| xjg| qdw| hst| bsf| jby| adr| fnf| xpx| wqp| bdr| paf| hnc|
