cfa

I'm unsure of how to test this hypothesis and would greatly appreciate your ideas: For illustrative purposes, let's assume that two groups of people (experts vs. novices) author a questionnaire with five scales (scale1 to scale5). Let's further assume that I have reason to hypothesize that when...

Hello, I'm running a cfa to examine a scale with 3 correlated factors (subscales) and 14 observed variables (items) and n=79 (which is actually, unfortunately way too small for cfa). The chi²-test is significant, so actually I should reject the model, but it is recommended to additionally...

Hello everybody, I'm running a cfa with the correlated factors and 14 indicator variables in R. For my multivariate outlier analysis I chose Generalized Cook's Distance. The result is: 10 outliers with a range from 1 to 50. To be honest my problem is that I have no idea 1. how to interprete...

Hi, Perhaps unwisely as a newcomer to stats, I have taken on a scale validation project. I’ve searched the literature and can’t find anything so this is the issue: I’m developing a scale that (hypothetically) will identify, differentiate and measure two different constructs occurring in...

Can someone please tell me the prerequisites to learn PCA? Is prior knowledge of CFA needed? I am new to the topic. Thanks in advance!

Hi all, Thoughts please. Obviously, AMOS is mainly used for confirmatory factor analysis (CFA) and structural equation modelling (SEM) - but can data from AMOS be used to populate an exploratory factor analysis (EFA) table as part of a measure development process? Specifically can AMOS...

I am trying to confirm the model for a 16-item measure. It has been confirmed for a homogeneous group, however, I want to determine if the model fits a heterogeneous (diverse) group. I ran a CFA using LISREL; however, the output for the fit tests are not within acceptable ranges. I have...

I have recently been performing confirmatory factor analysis to assess model fit for an established measure, the measure has previously been criticised for poor internal consistency in the relevant literature, but has yet to be administered for use in the UK. I am looking to assess a 15-item...

Folks, I am reading an article that tested 2 models--one with an hypothesized separate-factor relationship between five pairs of personality dimensions as measured by two personality assessments, the other with a hypothesized joint-factor relationship between the dimensions--using CFA and...

When using Bayesian MCMC in AMOS, do the MCMC algorithms allow for nonlinearity? I know all the other estimation algorithms do not [e.g. maximum-likelihood (ML)]. Also, does anyone know of any research articles that involve Bayesian CFA and measurement invariance that is similar or the same...

Hey Guys! I'm really having a bad time with this trouble in AMOS. What sould I do? Because of this, when I run the analysis it doenst show much.. Like, I cant see the loadings between the variables, for example.

Hi Hi. I am using LISREL 8.8 (Simplis Commands) I am stuck in doing 2nd order Multigroup measurement Invariance - specifically i cannot get through the stage for equal intercepts (strong invariance/Measurement intercepts) I kept having errors and model does not converge. Hope some one...

Hi, An existing questionnaire I am using (23 items, supposedly 2 subscales, N = 700) has shown poor fit to the 2-factor model as specified by its designers (confirmatory factor analysis yielded a CFI and TLI both <.70). Subsequently, I performed a CFA on the items of the subscale I am most...

Hi, Currently I am using Rstudio with the Lavaan package in order to perform a confirmatory factor analysis (CFA) on a dataset (N = ~ 700, 23 observed variables, 2 factors). The problem, however, is that the data are not even close to being multivariate normal, with a Mardia's kurtosis of 378...

I am trying to teach myself confirmatory factor analysis by working through examples in a textbook. The textbook only contains syntax for LISREL or SAS but I'm trying to learn it with R. When I estimate models without any equality constraints or correlated errors, I get the exact same output as...

Hello there. Does anyone know if there is any way to use the 'factoran' function in MATLAB to perform a Confirmatory Factor Analysis? Thank you so much and best wishes.

Hi stat freaks! :confused: I've just conducted an analysis of a scale's consistency (coeffs alpha, beta, omega, theta) and CFA to inspect the scale. I was wondering about the relation between Revelle's beta coeff. and CFA results. Beta coef. = estimates the worst possible split half of a item...

Hi, I'm new to R and I'm attempting to run a CFA model using the lavaan package. So far I have imported my data from SPSS and specified my model and I am now try to fit the model and am getting an error message (please see below syntax and error message) > SCS.model <- 'rank =~ SCS001 +...

Hi all, I was wondering what the core, meaningful differences are between Item Response Theory and Confirmatory Factor Analysis. I understand that there are differences in the calculations (focusing more on item vs. covariances; log-linear vs. linear). However, I have no idea what this...

Hello again Sorry - In relation to running Confirmatory Factor Analysis - I'm wondering whether someone is aware of RMSEA being impacted by high reliability scores ? As background, I understand that RMSEA can be affected by high factor loadings. Currently, I have a construct with 6...
