Izibalo Ezifundweni Zobulili Izibalo zidlala indima ebalulekile ekuqondeni izindaba zobulili ngendlela elinganisekayo, ehlelekile, nephendulayo. Izifundo zobulili azibheki nje kuphela okuhlangenwe nakho, ubunikazi, kanye nobudlelwano bamandla, kodwa futhi namaphethini omphakathi abonakala ngedatha: ukuthi ubani ofinyelela imfundo, ukuthi ubani osengozini enkulu yobudlova, ukuthi ubani othola umsebenzi osemthethweni, … Funda kabanzi
Izindlela Zokuqinisekisa Okuphambene Nezibalo Ezibalo kanye nesayensi yedatha, enye yezinselelo ezinkulu ukuqinisekisa ukuthi imodeli ayisebenzi kahle kuphela kudatha eqeqeshwe kuyo, kodwa futhi isebenza kahle kudatha entsha, engakaze ibonwe ngaphambili. Le nkinga ivame ukubizwa ngokuthi ukujwayelekile. Yilapho ukuqinisekiswa okuphambene kudlala khona indima ebalulekile… Funda kabanzi
Ukubaluleka Kwezibalo Ebudlelwaneni Bamazwe Ngamazwe Ubudlelwano bamazwe ngamazwe (IR) buvame ukuqondwa njengensimu ehlobene kakhulu nezingxoxo, izingxoxo, izingxabano, ukubambisana, kanye nokuguquguquka kwamandla phakathi kwezizwe. Kodwa-ke, ngemuva kwezinkulumo zabaholi, izivumelwano zamazwe amaningi, noma ukungezwani kwezepolitiki okuvezwa kwabezindaba, kulele ungqimba olubalulekile oluvame ukunganakwa: idatha. Yilapho izibalo zidlala khona indima ebalulekile. Izibalo azi… Funda kabanzi
Izibalo ku-Game Theory I-game theory iyigatsha lezibalo elifunda ukwenza izinqumo ngamasu lapho umphumela womdlali oyedwa uncike ezenzweni zabanye abadlali. Le mbono isetshenziswa kabanzi kwezomnotho, kwezebhizinisi, kwisayensi yezepolitiki, kwisayensi yamakhompyutha, ngisho nakwezebhayoloji yokuziphendukela kwemvelo. Kodwa-ke, empeleni, izimo zamasu azivamile "ukucaca" futhi zingabalwa ngokugcwele kusukela nje... Funda kabanzi
Ukuhlaziywa Kwezibalo Zocwaningo Lwezokwelapha Ukuhlaziywa kwezibalo kuyisisekelo esibalulekile ocwaningweni lwezokwelapha ngoba kusiza abacwaningi ukuguqula idatha yezokwelapha eyinkimbinkimbi ibe yimiphumela eqondakalayo nephendulayo. Esimweni sezokwelapha, izinqumo ezisekelwe emiphumeleni yocwaningo zingathinta ngqo ukuxilongwa, ukwelashwa, izincomo zenqubomgomo, ngisho nokuphepha kwesiguli. Ngakho-ke, ukuqonda okuhle kwezimiso ze… Funda kabanzi
Amasu Okubona Idatha Kuzibalo Ukubona idatha kungenye yezici ezibaluleke kakhulu zezibalo zanamuhla. Phakathi kobuningi bedatha evela ezinhlolovo, ekuhlolweni, ekuthengisweni kwedijithali, nasezinzwa, inselelo enkulu akukhona nje ukubala izinombolo kodwa futhi nokudlulisa incazelo ngemuva kwalezo zinombolo. Yilapho ukubonakala kwedatha kungena khona: ukuguqula idatha eluhlaza ibe yizibonisi ezilula ukuziqonda, ukusiza ukuthola… Funda kabanzi
Izibalo Ekuhlaziyweni Kwezingozi Ezweni eligcwele ukungaqiniseki—kusukela ekushintsheni kwemakethe kanye nokushintsha kwesimo sezulu kuya ezingozini zezempilo kanye nokuphazamiseka kweketanga lokuhlinzeka—sidinga indlela ehlelekile yokuqonda nokuphatha ingozi. Yilapho izibalo zidlala khona indima ebalulekile. Izibalo aziyona nje iqoqo lamafomula, kodwa kunalokho isethi yezindlela zokuguqula idatha ibe ulwazi olungasetshenziswa ukulinganisa amathuba esigameko, … Funda kabanzi
Ziyini Izinkolelo-mbono Ezingenamsebenzi Nezinye? Ezindleleni zezibalo kanye nocwaningo, amagama athi null hypothesis (H0) kanye ne-alternative hypothesis (H1 noma Ha) yimibono emibili eyisisekelo evame ukuvela lapho abacwaningi befuna ukuhlola i-hypothesis besebenzisa idatha. Zakha isisekelo sokuhlolwa kwe-hypothesis, okuyinqubo yokunquma ukuthi ubufakazi obuvela kusampula bunamandla ngokwanele yini ukusekela i-hypothesis. Funda kabanzi
Izindlela Zokufaka Izibalo Ekwenzeni izibalo nokuhlaziywa kwedatha, inkinga yokuntuleka kwedatha cishe njalo iphakama. Idatha ingalahleka ngenxa yokuthi abaphenduli abayiphenduli imibuzo ethile, amaphutha okurekhoda, ukwehluleka kwezinzwa, ukonakala kwedatha ngesikhathi sokukhipha, noma ngenxa yenqubo yokuhlanganisa imithombo eminingi yedatha engahambisani ngokugcwele. Uma ingaphathwanga kahle, idatha engekho inganciphisa… Funda kabanzi
Ifomula Yokugoba Kwe-Logistic Ugoba kwe-Logistic kungenye yezindlela ezithandwa kakhulu kwizibalo kanye nesayensi yedatha yokulingisa ubudlelwano phakathi kwenani lezinto eziguquguqukayo ezizimele (izibikezelo) kanye nogoba oluxhomeke kusigaba, ngokuvamile oluyi-binary (isb., yebo/cha, impumelelo/ukwehluleka, ukugula/okunempilo). Ngokungafani nogoba oluqondile, olukhiqiza amanani aqhubekayo, ugoba kwe-logistic kuklanyelwe ukulinganisa amathuba omcimbi, ngakho-ke... Funda kabanzi
