What is profile analysis in psychology?

A profile analysis is a multivariate statistical technique designed to compare groups of individuals using both the shape of their score profiles on a variety of subjects and to the value of the scores the attained on those variables.

How does latent profile analysis work?

Latent Profile Analysis (LPA) tries to identify clusters of individuals (i.e., latent profiles) based on responses to a series of continuous variables (i.e., indicators). LPA assumes that there are unobserved latent profiles that generate patterns of responses on indicator items.

What is LPA analysis?

Abstract. Latent profile analysis (LPA) is a categorical latent variable approach that focuses on identifying latent subpopulations within a population based on a certain set of variables.

What is the difference between latent class analysis and latent profile analysis?

In this chapter, I will introduce latent profile analysis (LPA) and latent class analysis (LCA) which are mixture models for cross-sectional data. The main difference between them is that LPA applies to continuous response variables, whereas LCA applies to categorical ones.

What is profile testing?

an overall description or summary of an individual’s relative standing or characteristics obtained by collating the findings from a series of tests or subtests.

What is profile analysis in school psychology?

A controversial aspect of this debate relates to the utility of cognitive profile analysis, a class of interpretive methods that encourage practitioners to make diagnostic decisions and/or treatment recommendations based on the strengths and weaknesses observed in ability score profiles.

What is growth mixture modeling?

Growth mixture modeling (GMM) is a method for identifying multiple unobserved sub-populations, describing longitudinal change within each unobserved sub-population, and examining differences in change among unobserved sub-populations.

Is latent profile analysis a mixture model?

mix. A different name for latent profile analysis is “gaussian (finite) mixture model” and a different name for latent class analysis is “binomial (finite) mixture model”. Its Bayesian version is popular in the computer science literature as “latent Dirichlet allocation”.

What is Bayesian latent class analysis?

Latent class analysis is based on the assumption that within each class the observed class indicator variables are independent of each other. We explore a new Bayesian approach that relaxes this assumption to an assumption of approximate independence. Simulation studies and real data analysis are conducted using Mplus.

Why profile test is done?

The lipid profile test is needed to check for dyslipidaemia symptoms, it is also carried out to check adults and children who are risk prone to high blood cholesterol value and triglycerides. This happens because of development of diabetes, high blood pressure or a heart disease.

What is an example of a profile test?

Commonly used personality tests include the Myers-Briggs Type Indicator (MBTI), the Minnesota Multiphasic Personality Inventory (MMPI), and the Sixteen Personality Factor Questionnaire.

What is a cognitive profile?

A cognitive profile is an individual’s pattern of relative strengths and difficulties across several cognitive domains.
