random chain data

how i liberate little volume information futile method many incomparable volume data?

for example, i have several thousand lines 'real' data, i wish insert dozen twin lines control information futile method via 'real' data.

now i am perplexing ask futile array generators, i am seeking statistical question, i know beget futile numbers, nonetheless doubt i pledge information extrinsic futile method while during same being sincerely regularly sparse by file.

if i only rest generating futile numbers there luck (albeit unequivocally little one) control data, during slightest clumps it, extrinsic within sincerely slight preference 'real' data. best proceed stop happening?

to word another way, i wish insert control information via genuine information but there being proceed third jubilee calculate rows control real.

update: i have finished 'community wiki' anyone wants correct doubt creates some-more clarity following right ahead.

update: let me try an instance (i wish libel height contingent coding question, statistical question).

• i have 3000 rows 'real' information (this volume change run run, depending volume information user has).


• i have 20 rows 'control' information (again, change depending array control rows user wants use, anything 0 upwards).

i wish insert 20 'control' rows roughly after each 150 rows 'real' information extrinsic (3000/20 = 150). however i wish accurate as i wish control rows identifiable simply formed plcae cost data.

therefore i mind some 'control' rows being clumped together there some sections unequivocally few 'control' rows during all, nonetheless generally i wish 'control' rows sincerely regularly distributed via data.
