    Negative values in a Pattern Matrix after Exploratory Factor Analysis

    Thanks for the reply Spunky, Yes Monte Carlo is Horn's Parallel Analysis. And yes, when I first saw it I thought I had made a coding error. Still hoping I have to be honest, will triple check... As it stands at the moment my values on factor 1 range from 0.50 to 0.82, and on factor 2 range...

    Negative values in a Pattern Matrix after Exploratory Factor Analysis

    Hi, I've run an EFA (Principle Axis Factoring) with an Direct Oblimin rotation to pilot some scale items. I have two cleanly loading factors in the Pattern Matrix (confirmed by Scree plot and Monte Carlo). Alpha is high for both. However - The first factor only has positive values, the second...

    spunky THANK-YOU this is the answer I have been trying to prise out of my supervisor for weeks, I just had this nagging feeling.... No, I will not be touching multilevel FA with a barge-pole at this point in my limited experience! Plus I only use SPSS and I don't think it even does that...

    Factor Analysis newbie seeks your help

    Yes, that is the case. The theory I'm basing the scale on supposes that there is a qualitative difference in parental-child dyads, and the 2 constructs may or not be present in each separate dyad relationship. So I thought I could treat each completed response individually and separately for...

    Factor Analysis newbie seeks your help

    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...
