This is probably because each region is different in terms of demographics, employment and health indicators, factors that are known to impact on rates of placement in institutions.
As standard, one indicator factor loading was set to one, and correlations between the underlying latent factors were free to be estimated.
The multiple-indicator factor tradition includes works by Thurstone [ 1], Harman [ 2], Lawley & Maxwell [ 3], and Mulaik [ 4], while the single-indicator path tradition has roots in regression and includes Wright [ 5, 6], Blalock [ 7], Duncan [ 8], and Heise [ 9].
Generally, Ellenberg's indicator factors indicated that the plots were sampled in cold climates and acidic soils with slightly more open and acidic habitats in the Alps than in the Scandes and slightly more continental and humid habitat in the Scandes than in the Alps (Figure S1).
For the first model, we tested for configural invariance which indicates whether the number of factors and pattern of indicator-factor loadings is identical.
While most neural-system-based climate expectation tests have been led by meteorologists or climate specialists, there is a lot of debate encompassing the estimation from the earlier information in deciding indicator factors (Saba and Rehman 2012).
Displaying the selected plots along the indicator values separately showed that the 403 Alps Scandes pairs were sampled in similar conditions for all six Ellenberg's indicator factors (Figure S2).
The plot values for each of the six Ellenberg's indicator factors as well as plot size were used to compute seven separate Euclidian distance matrices in each of the two regions.
To account for these imperfections in the pairing, we used the six Ellenberg's indicator factors and plot size or transformations of these variables as covariates in the subsequent models of β- and α-diversity.
