    Study Notes

    Componentes Essential del Equation de Regression Lineare

    • Le componentes essential del equation de regression lineare include le coefficiente de regression (β), le intercepto (α), e le variable independent (x) e dependent (y).

    Assumpciones del Modello de Regression Lineare

    • Le assumpciones importante in un modello de regression lineare include:
      • Linealitate: le relation inter le variable independent e dependent es lineare
      • Independentia: le errores es independent inter se
      • Homoscedasticitate: le varianza del errores es constante
      • Normalitate: le errores es distribuite normalmente
      • Non-correlation: le errores non es correlate con le variable independent

    Rol del Gradient in Regression Lineare

    • Le gradient in regression lineare es un indicator del direction e del magnitude del cambio in le variable dependent quando un del variable independent es cambiate.

    Errores Commun in Regression Lineare

    • Un errore commun in regression lineare es le problema de multicollinearitate, quando duo o plus variable independent es altamente correlate inter se.

    Indicator de un Bon Modello de Regression Lineare

    • Un indicatore de un bon modello de regression lineare es le coefficiente de determination (R²), que mesura le proportion del varianza explorate per le modello.
