Thaum xaiv tus qauv linear, cov no yog cov hauv qab no:

  1. Tsuas yog sib piv cov qauv linear rau tib dataset.
  2. Nrhiav ib qauv nrog lub siab kho R2.
  3. Nco ntsoov qhov no qauv muaj sib npaug faib seem nyob ib ncig ntawm xoom.
  4. Xyuas kom tseeb tias qhov yuam kev ntawm qhov no qauv yog nyob rau hauv ib tug me me bandwidth.

Ntawm no, thaum twg koj yuav tsum siv ntau regression?

Ntau yam kev thim rov qab yog ib tug extension ntawm yooj yim linear regression . Nws yog siv thaum peb xav rau kwv yees tus nqi ntawm qhov sib txawv raws li tus nqi ntawm ob lossis ntau dua lwm qhov sib txawv. Qhov sib txawv peb xav rau kwv yees yog hu ua qhov sib txawv ntawm qhov sib txawv (lossis qee zaum, qhov tshwm sim, lub hom phiaj lossis cov qauv sib txawv).

Tom qab ntawd, lo lus nug yog, kuv yuav xaiv tus qauv li cas? Yuav Ua Li Cas Xaiv Tus Qauv Kawm Tshuab - Qee Cov Lus Qhia

  1. Sau cov ntaub ntawv.
  2. Txheeb xyuas qhov tsis txaus ntseeg, cov ntaub ntawv ploj thiab ntxuav cov ntaub ntawv.
  3. Ua statistical tsom xam thiab pib pom.
  4. Tsim qauv.
  5. Xyuas qhov tseeb.
  6. Qhia qhov tshwm sim.

Tsuas yog li ntawd, qhov sib txawv ntawm cov qauv regression yog dab tsi?

Hom Regression

  • Linear Regression. Nws yog qhov yooj yim tshaj plaws ntawm regression.
  • Polynomial Regression. Nws yog ib qho txheej txheem kom haum ib qho kev sib npaug nonlinear los ntawm kev ua haujlwm ntawm polynomial ntawm kev ywj pheej sib txawv.
  • Logistic Regression.
  • Quantile Regression.
  • Ridge Regression.
  • Lasso Regression.
  • Elastic Net Regression.
  • Thawj Cheebtsam Regression (PCR)

Yuav siv ntau npaum li cas cov kev hloov pauv ywj pheej tuaj yeem siv hauv ntau qhov kev hloov pauv?
