Primerjava programov za standardizacijo časovnih vrst v dendrokronologiji = Comparison of two programs for standardisation of time-series data in dendrochronologyPoljanšek, Simon ; Jagodic, Špela ; Levanič, TomZa standardizacijo zaporedij širin branik je v uporabi več programov, mi smo primerjali dva - najbolj razširjeni in znani program ARSTAN in pred kratkim predstavljeno knjižnico za standardizacijo ... dendrokronoloških podatkov dplR, narejeno za statistični program R. Oba programa sta brezplačna, ARSTAN je namenski program za standardizacijo zaporedij širin branik, medtem ko je program R, v okviru katerega deluje knjižnica dplR, namenjen tudi drugim analizam in prikazom podatkov. Uporabili smo različne teste in preverili, ali so med kronologijami širin branik, kakor jih izračunata ARSTAN in dplR, statistično značilne razlike in ali so standardizirane kronologije, narejene s knjižnico dplR, enako uporabne za preučevanje ekoloških in klimatoloških vprašanj, kot so kronologije, narejene s programom ARSTAN. ARSTAN za izračun kronologije ponudi uporabniku listo ukazov, medtem ko dplR zahteva pisne ukaze in ne ponuja izbire. Pri primerjavi rezultatov smo ugotovili, da razlike med izračuni primerjanih programov niso statistično značilne - programa pri osnovnih statističnih parametrih ponudita enake rezultate za povprečne širine branik in standardne odklone ter z razliko na drugem decimalnem mestu za rezultate občutljivosti in avtokorelacijskega koeficienta. Korelacija med standardiziranima kronologijama znaša 0,9773, med kronologijama ostankov pa 0,9776, grafično so razlike prav tako maloštevilne in majhne. Ker se programa razlikujeta le po delovnem okolju, je odločitev o izbiri programa prepuščena uporabniku.Source: Zbornik gozdarstva in lesarstva = Research reports : forest and wood science & technology. - ISSN 0351-3114 (Št. 93, 2010, str. 11-22)Type of material - article, component part ; adult, seriousPublish date - 2010Language - slovenianCOBISS.SI-ID - 3088806
