risk to the patient. Screening tests should have high diagnostic sensitivity, which means few false negative results would be expected, as the goal of testing is to rule out the presence of disease. Screening tests should be used to screen for diseases that (1) have serious consequences if left undetected, (2) are reasonably prevalent within the population, and (3) have treatment options readily available. Should a positive result be obtained, a more accurate, confirmatory test should then be performed. One example of a screening test would be the urine cortisol-to-creatinine ratio (Cort:Crt)u, which is used to screen symptomatic patients for canine hyperadrenocorticism.[1,2] The (Cort:Crt)u ratio tests for the presence or absence of urinary cortisol excretion and is noninvasive and inexpensive. It also has a high diagnostic sensitivity, which means that a negative result strongly indicates that the patient most likely does not have the disease.[1,2]
motivatsioon) Faktorite arvutamine kaudsete mõõtmiste kaudu (nt küsimustikud) – põhineb korrelatsioonimaatriksil ehk tugineb muutujate omavahelistele seostele. Tüübid: o Uuriv faktoranalüüs (exploratory FA) – eesmärk otsida andmetest ühiseid latentseid faktoreid; kõige levinum ja kõige enam kasutatud ka seminaritöödes o Kinnitav faktoranalüüs (confirmatory FA) – tahame teada, kas hüpoteetiline mudel on parem kui mõni alternatiivne mudel o Peakomponentide analüüs (principal components analysis) – eesmärk on välja selgitada väiksem hulk komponente, mis vastutavad esialgsete muutujate varieeruvuse eest. Nimetatakse ka andmete taandamiseks. Faktoranalüüs proovib seletada ühist osa varieeruvusest ning peakomponentide analüüs proovib seletada kogu variatiivsust.
