Question indicator reliability in JASP
I'm reading Todd et al. (2017) and their best practice recommendations for SEM, and they mention indicator reliability: 'refers to the proportion of variance in each measured variable that is accounted for by the latent factor it supposedly represents (O’Rourke & Hatcher, 2013). Calculating IR is straightforward as it merely involves squaring the standardized factor loading for each measured variable'.
I was just wondering if this would be the same as Rsquared in JASP, when doing a SEM analysis?
Also they refer to average variance extracted (AVE) as a way to measure discriminant validity; and I was wondering if there is a function in JASP for SEM models that can do that?
Thanks in advance for your help.
