latent variable

Hi, I am working with a binary outcome model so yi takes the value 1 or 0. Xi is a vector of 8 explanatory variables and Beta (B) is a vector of 9 parameters (8 variables +intercept). I am working with the probit model so F(X'B)=standard normal c.d.f. Next; Let y(hat)i be equal to...

Hi all, I just ran my model, and it fits really well and all the parameter coefficients are strong and at least moderately high. I was confused though because the Variance reported above the latent variable is zero. The model's structure is four measured variables loading into a single latent...

hi i have 2 main questions Latent variables are unobserved variables that are measured by multiple observed items(called manifest variables). now my questions: 1- each latent variable is an unobserved variable are all unobserved variable called "latent"? 2- each manifest...

Hi all, Does anyone know if it is OK to use an ordered probit model to predict a latent variable, e.g. self-perceived health; and then use the linear predictions as a right-hand side variable in another ordered probit to predict a different latent variable, e.g. life satisfaction. The...

Hello, I am having trouble with a Structural Equation Model. As you can see in the attached picture, my main outcome variable (F4) is a latent variable. When I run the model, all of the paths are significant in the hypothesized direction, but the Chi-square is very high (almost 10,000) and...

Hello. My two previous posts (1 & 2) have about 100 views each, but no replies, so I must have done a poor job asking the question. So, here is the general question: how can I run a run a multivariate (more than one non-independent, response variables) ordered probit regression model? I've...

Hi all, I am relatively new to R. I have been using it to estimate structural equation models using OpenMx. Now I am trying to fit a latent curve model using a script that I have used many times, but now I get an error which I cannot find a solution to! I don't know whether I should...

Hi all, I seem to recall that some of you (spunky, Dason, and other) might be doing research using latent variable models and their variants. As I start to ask more questions about the temporal sequences of signaling, aggression, and courtship in my experiments on birds (and now spiders)...

For exploratory purposes, should PCA (Principal Component Analysis) be done for one latent variable at a time or should it done for all the latent variables at once? I seem to get better results with each of my latent construct's item loadings if I do PCA one latent construct at a time. Is this...

Hi, I'm doing some research for my dissertation and need to construct a latent variable that includes observations of various economic determinants (IVs). I'm using SPSS, but I don't have access to AMOS, and a additive composite index lacks reliability (Cronbach's Alpha is too small)...
