În cuprinsul prezentei lucrări sunt examinate valenţele indicatorului “coeficientul de determinare standardizat”, propus de autor, pentru cuantificarea eficienţei utilizării variabilelor explicative şi a ierarhizării condiţiilor care trebuie îndeplinite în cazul unor teste statistice prin care se cuantifică de regulă eficienţa adăugării unei noi variabile explicative în cadrul unui model de regresie liniară. De asemenea, este scos în evidenţă rolul valorilor calculate ale testului Fisher ca premisă pentru ca adăugarea unei noi variabile explicative în modelul de regresie liniară să fie eficientă.
