\u010cl\u00e1nek se zam\u011b\u0159uje na r\u016fzn\u00e1 hodnocen\u00ed vztah\u016f mezi kategori\u00e1ln\u00edmi prom\u011bnn\u00fdmi a jejich aplikaci na problematiku v\u00fdb\u011bru vysv\u011btluj\u00edc\u00edch prom\u011bnn\u00fdch v klasifika\u010dn\u00edch stromech. Jsou jednak diskutov\u00e1ny postupy dostupn\u00e9 v komer\u010dn\u00edch programov\u00fdch syst\u00e9mech (ch\u00ed-kvadr\u00e1t testy a porovn\u00e1v\u00e1n\u00ed variability vysv\u011btlovan\u00e9 prom\u011bnn\u00e9 v r\u016fzn\u00fdch skupin\u00e1ch objekt\u016f pomoc\u00ed Giniho m\u00edry a entropie), jednak nazna\u010deny dal\u0161\u00ed mo\u017enosti v\u00fdvoje v t\u00e9to oblasti. St\u00e1vaj\u00edc\u00ed postupy jsou ilustrov\u00e1ny na anal\u00fdze dat v programov\u00e9m syst\u00e9mu IBM SPSS Decision Trees. V\u00fdzkum se v posledn\u00ed dob\u011b zam\u011b\u0159uje na hodnocen\u00ed jednostrann\u00e9 z\u00e1vislosti ordin\u00e1ln\u00ed vysv\u011btlovan\u00e9 prom\u011bnn\u00e9 na prom\u011bnn\u00e9 nomin\u00e1ln\u00ed a implementaci v r\u00e1mci klasifika\u010dn\u00edch strom\u016f. Takov\u00e9 p\u0159\u00edstupy ji\u017e byly realizov\u00e1ny v bal\u00ed\u010dc\u00edch v prost\u0159ed\u00ed R.<\/p>\n
