Kuyerekeza phukusi la Python pakuwunika kwa mayeso a A / B (ndi zitsanzo zama code)

Chiyambi: Mphamvu ndi Zoyipa Zakuyesa kwa A/B

Kuyesa kwa A/B ndi mwala wapangodya wa kupanga zisankho motsogozedwa ndi deta, zomwe zimalola mabizinesi kupitilira malingaliro a m'matumbo ndikupanga zisankho zoyenera mothandizidwa ndi umboni wotsimikizika. Kaya mukuyesa masanjidwe atsopano a webusayiti, mutu wa imelo yotsatsa, kapena chinthu chomwe mwagulitsa, kuyesa kwa A/B kochitidwa bwino kungakhudze kwambiri ma metrics. Komabe, ulendo wochoka ku data yoyesera mpaka kutsimikizira komveka bwino, molingana ndi ziwerengero ukhoza kukhala wovuta kwambiri. Apa ndipamene Python, yokhala ndi malo osungiramo mabuku a sayansi ya data, imakhala chida chofunikira kwambiri. Zimapatsa mphamvu akatswiri ndi mainjiniya kuti azisanthula mozama zotsatira, koma ndi mapaketi angapo amphamvu omwe alipo, kusankha yoyenera kungakhale kovuta. M'nkhaniyi, tifanizira ma phukusi odziwika bwino a Python osanthula mayeso a A/B, odzaza ndi zitsanzo zama code kuti zikuwongolereni momwe mungagwiritsire ntchito.

Scipy.stats: Njira Yoyambira

Kwa iwo amene ayamba ndi kuyesa kwa A/B kapena amene akufunika njira yopepuka, yopanda frills, gawo la `scipy.stats` ndilomwe mungasankhire. Imapereka ntchito zowerengera zofunikira pakuyesa kwamalingaliro. Kayendesedwe ka ntchito kamaphatikizapo kugwiritsa ntchito mayeso ngati t-test ya Student kapena Chi-squared test kuti muwerengere p-value. Ngakhale kuti ndi yosinthika kwambiri, njira iyi imafuna kuti muzigwira ntchito pokonzekera deta, kuwerengera nthawi yodalirika, ndikutanthauzira zomwe zatulutsidwa. Ndi njira yamphamvu koma yothandiza.

"Kuyambira ndi `scipy.stats` kumapangitsa kumvetsetsa mozama za ziwerengero zomwe zili zofunika kwambiri, zomwe ndizofunika kwambiri kwa katswiri wa data."

Nachi chitsanzo cha kuyesa kwa t kuyerekeza mitengo yotembenuka pakati pamagulu awiri:

``` python kuchokera ku scipy import stats import numpy monga np # Zitsanzo za data: 1 pakutembenuka, 0 osatembenuka gulu_a = np.array([1, 0, 1, 1, 0, 0, 1, 0, 0, 1]) # 4 kusintha kwa 10 gulu_b = np.array([1, 1, 0, 1, 1, 1, 0, 1, 1, 0]) # 7 kusintha kwa 10 t_stat, p_value = stats.ttest_ind(gulu_a, gulu_b) sindikiza (f"T-chiwerengero: {t_stat:.4f}, P-mtengo: {p_value:.4f}") ngati p_value <0.05: print("Kusiyana kwakukulu kwapezeka!") zina: print("Palibe kusiyana kwakukulu komwe kwapezeka.") ```

Statsmodels: Comprehensive Statistical Modeling

Mukafuna zambiri komanso mayeso apadera, `statsmodels` ndi njira ina yapamwamba kwambiri. Amapangidwa makamaka kuti azitsatira ziwerengero ndipo amapereka chidziwitso chowonjezereka chogwirizana ndi zochitika zoyesa za A/B. Pamagawo a data (monga ma conversion rates), mutha kugwiritsa ntchito `proportions_ztest`, yomwe imayang'anira zokha ziwerengero za mayeso, p-value, ndi nthawi zodalirika. Izi zimapangitsa kuti code ikhale yoyera komanso zotulukapo zake kukhala zosavuta kuzimasulira poyerekeza ndi njira yoyambira ya `scipy.stats`.

``` python lowetsani statsmodels.stats.proportion monga gawo # Kugwiritsa ntchito kuwerengera kwachipambano ndi kukula kwa zitsanzo kupambana = [40, 55] # Chiwerengero cha otembenuka mu Gulu A ndi B nobs = [100, 100] # Ogwiritsa ntchito onse mu Gulu A ndi B z_stat, p_value = proportion.proportions_ztest(kupambana, nobs) sindikiza (f"Z-chiwerengero: {z_stat:.4f}, P-mtengo: {p_value:.4f}") ```

Malaibulale Apadera: Njira Yosavuta Kwambiri Yozindikira

Kwa magulu omwe amayesa mayeso a A/B pafupipafupi, malaibulale apadera amatha kufulumizitsa kusanthula. Maphukusi ngati `Pingouin` kapena `ab_testing` amapereka ntchito zapamwamba zomwe zimatulutsa chidule cha mayeso mumzere umodzi wa code. Chidulechi nthawi zambiri chimaphatikizapo p-value, nthawi yodalirika, kuthekera kwa Bayesian, ndi kuyerekezera kwa kukula kwake, zomwe zimapereka chithunzi chonse cha zotsatira za kuyesa. Izi ndizoyenera kuphatikiza kusanthula m'mapaipi odzipangira okha kapena ma dashboard.

• Scipy.stats: Zoyambira, zosinthika, koma zamanja.
• Statsmodels: Zotulutsa mwatsatanetsatane, ndizabwino kwa oyeretsa mawerengero.
• Pingouin: Zosavuta kugwiritsa ntchito, ziwerengero zachidule zatsatanetsatane.
• ab_testing: Amapangidwa makamaka kuti aziyesa A/B, nthawi zambiri amakhala ndi njira zaku Bayesian.

Chitsanzo pogwiritsa ntchito laibulale yongopeka ya `ab_testing`:

``` python # Chitsanzo chongopeka cha library yapadera kuchokera ku ab_testing import analyze_ab_test zotsatira = analyze_ab_test( group_a_conversions=40, gulu_a_total=100, group_b_conversions=55, gulu_b_total=100 ) sindikiza (zotsatira.summary()) ```

Kuphatikiza Kusanthula mu Bizinesi Yanu Kayendetsedwe Kantchito

Kusankha phukusi loyenera ndi gawo chabe lankhondo. Kufunika kwenikweni kwa kuyezetsa kwa A/B kumazindikirika pomwe zidziwitso zimaphatikizidwa bwino mubizinesi yanu. Apa ndipamene ma modular bizinesi OS ngati Mewayz amapambana. M'malo mokhala ndi zolemba zomwe zili mu kabuku ka Jupyter, Mewayz imakulolani kuti muyike mayendedwe onse owunikira mubizinesi yanu. Mutha kupanga gawo lomwe limakoka data yoyesera, kuyendetsa kusanthula pogwiritsa ntchito phukusi lomwe mumakonda la Python, ndikungodzaza dashboard yowonekera ku gulu lonse. Izi zimapanga chikhalidwe cha kuyesa koyendetsedwa ndi deta, kuonetsetsa kuti chisankho chilichonse, kuchokera ku chitukuko cha mankhwala kupita ku malonda a malonda, chimadziwitsidwa ndi umboni wodalirika. Potengera kusinthasintha kwa Mewayz, mutha kupanga zoyeserera zolimba za A/B zomwe zimakhala zamphamvu komanso zofikirika.

Mafunso Ofunsidwa Kawirikawiri
