Mayelana nalolu hlelo lokusebenza

I-APP Factors Analysis ye-Android iqukethe izingxenye ezintathu, eyodwa iwukucubungula amasampula okuguquguquka okungahleliwe; i-secondis factorization ye-matrix yokuhlanganisa; kanye nesibali sesithathu sokusabalalisa kwezibalo okwaziwayo.

Ingxenye yokucubungula amasampula okuguquguquka okungahleliwe iklanyelwe ukugcina (ahleliwe, asusiwe, aqanjwe kabusha) amasampula okuguquguquka okungahleliwe, ukuze kubalwe izici zawo eziyisisekelo zezibalo njenge: -ivelu eyisilinganiso; - ukuchezuka okujwayelekile; - skewness kanye kurtosis; - ukubala izikhawu zokuthembela yenani elimaphakathi; - ukuhlukahluka kanye nokuchezuka okujwayelekile; - hlola ukuthi isampula livela kokuguquguqukayo okujwayelekile noma okusatshalaliswe ngokulinganayo kusetshenziswa umbandela we-Pearson; - hlola ukuthi isampula isuka kokujwayelekile, okufanayo nangokusatshalaliswa okungahleliwe okungahleliwe usebenzisa umbandela we-Kolmogorov-Smirnov; - futhi zero skewness kanye kurtosis; - i-histogram enqunyiwe yesampula; - ukuhlolwa kokusebenza kwemibono ehlobene nencazelo kanye nokuchezuka okujwayelekile; nokunye.
Uhlelo lokusebenza lunomsebenzi wokusabalalisa okushelelayo, lokhu kufaka phakathi izimpahla zokusabalalisa okulungisiwe (okushelelayo) okuhlobene nesampula, okungakhishiwe kumbandela wokunquma we-Pearson's kanye ne-Kolmogorov-Smirnovr.
Engxenyeni ethi Factors Analysis for correlation matrix factorization isebenzisa izindlela ezimbili ezaziwayo: izingxenye eziyinhloko (Pearson, 1901 and Hoteling, 1933); kanye - izici eziyinhloko (uSpearman, 1904 1926). I-matrix yokuhlanganisa ingatholwa ngokuphathwa kwedatha nemisebenzi yohlelo lokusebenza, noma ngokufaka noma ukungenisa ekusetshenzisweni kwamatrices alungele ukuhlobana.
Amasampula, imiphumela yokucubungula kanye ne-histogram ingagcinwa. Amathebula anale datha angathunyelwa, futhi athunyelwe ukuze alondolozwe futhi aphrinte. Uhlelo lokusebenza lunemisebenzi yokwakha, ukususa nokukhetha ifolda yemiphumela yedatha yokugcina.

I-Factor Analysis ye-Android

Uhlelo lokusebenza lwe-Factors Analysis lwe-Android luqukethe izingxenye ezintathu, eyodwa iwukucubungula amasampula okuguquguquka okungahleliwe; i-secondis factorization ye-matrix yokuhlanganisa; kanye nesibali sesithathu sokusabalalisa kwezibalo okwaziwayo.

uhlelo lokusebenza ukugcina amasampula amaningi okuguquguqukayo okungahleliwe nokubala i-matrix yokuhlanganisa
isampula yokucubungula okuguquguqukayo okungahleliwe
hlola ukuthi isampula livela kokuhluka okujwayelekile noma okusatshalaliswe ngokulinganayo kusetshenziswa umbandela we-Pearson; kanye nenqubo ye-Kolmogorov-Smirnovr
i-histogram enqunyiwe yesampula;

isebenzisa izindlela ezimbili izingxenye eziyinhloko kanye nezici eziyinhloko zokuhlanganisa i-matrix factorization
ukubala amathuba akhulayo noma okuguquguqukayo okungahleliwe
idatha yemiphumela ingathunyelwa futhi ithunyelwe nge-inthanethi
dala, susa bese ukhetha ifolda ukuze uthole imiphumela yedatha yokugcina

ama-hypotheses, i-histogram okungenzeka okungahleliwe ukusatshalaliswa kwezibalo okuhambisanayo kwe-matrix factorization izici eziyinhloko
