    Mixed Logit Regression Problem with AIC / BIC

    Hi, I am new to this forum and have trouble with my mixed logit regression model. I have conducted an experiment with 169 participants who each performed 5 brand choice decisions (Buy brand A vs. Buy brand B). In each decision, there was a different product type (e.g. laundry detergent...

    Latent Growth Curve and covariates

    I'm examining latent growth curves in Mplus. My dependent variable is continuous, measured over three time points. I have a great unconditional model, and now I want to examine multiple time-invariant predictors on the latent intercept and slope. If I add the predictors, how do I evaluate if...

    Bayes Factors using BIC statistic (model selection)

    Hi, I need to compare four different models (logistic regression), model selection is performed using bayes factors using the BIC statisic. BIC can be transformed to the probability of the data given a model: PrBIC(D|Hi) = exp[-BIC(Hi)/2] And so, we can compute the Bayes factors...

    Model selection for logistic regression, comparing p-value approach, BIC and CV.

    Hi, I need to write a discussion on three approaches of model selection; p-value, Bayes factors (using BIC) and leave-one-out cross validation. The p-value is not preferred, statiscal significance depends on sample size, p-value is based on imaginary data, depends on the intentions of the...

    [STATA - Lag length criteria]: How can I explain the results?

    Good evening everyone. I got different output from the code: forval i = 1/118 { varsoc Illiq`i', maxlag(10) } that describes AIC,BIC,... lag information criterion, but I don't know how I can interpret them. How can I choose the correct number of lags on the basis of all these output...

    [AMOS] No BIC value given

    I would like to test two different (and competing) CFA-models in AMOS. Both of the these used the same nine manifest variables. In one of them, there are four latent variables, in the other two. After doing some (admittedly not extremely thorough) research on model comparisons I had planned to...

    Model comparison in psychophysics with multiple participants

    Hi, I have a quite general methodological question about model comparison. I ran a psychophysical experiment in which each participants performed ~500 trials of a perceptual decision task. My observation are reaction times. I want to compare several possible model to find which one explains...
