Ntawm no, yuav ua li cas koj xam sinusoidal regression?

Sinusoidal Regression . Kho qhov tseem ceeb ntawm A, B, C, thiab D hauv qhov kev sib npaug y = A*sin(B(x-C))+D to make a sinusoidal nkhaus haum ib pawg ntawm randomly generated cov ntaub ntawv. Thaum koj muaj kev ua haujlwm zoo, nyem rau ntawm "Show Computed" kom pom cov suav regression kab. Siv "ctr-R" los tsim cov ntaub ntawv tshiab thiab sim dua.

Tsis tas li ntawd, dab tsi yog sinusoidal regression? Lub laij lej yuav muab rau regression equation in the form: y = a sin (bx + c) + d. qhov twg | ib | yog qhov amplitude, b yog qhov zaus (qhov twg b> 0), 2π / b yog lub sijhawm, | c | / b yog kab rov tav ua haujlwm (rau sab xis yog c 0) thiab d yog txoj haujlwm ntsug (nce yog d> 0 thiab nqes yog d <0).

Hais txog qhov no, dab tsi yog trigonometric regression?

Trigonometric Regression . Qhov no yog qhov tseem ceeb ntawm txoj kev haum rau lub sijhawm. regression muaj nuj nqi rau cov ntaub ntawv ntawm daim ntawv {yi, ti; i = 1, 2,, n}, qhov twg y yog cov lus teb sib txawv thiab t feem ntau qhia lub sijhawm.

Dab tsi yog sinusoidal graph?

A sinusoidal muaj nuj nqi yog ib tug muaj nuj nqi uas zoo li ib tug sine muaj nuj nqi nyob rau hauv lub siab hais tias lub functionality yuav ua tau los ntawm kev hloov, stretching los yog compressing lub sine muaj nuj nqi. Yog tias tsim nyog koj tuaj yeem xav tshuaj xyuas cov daim duab luv luv.
