Žiberna","doi":"10.51936/orxk5673","DOIUrl":"https://doi.org/10.51936/orxk5673","url":null,"abstract":"The paper starts with an observation that the blockmodeling of relatively sparse binary networks (where we also expect sparse non-null blocks) is problematic. The use of regular equivalence often results in almost all units being classified in the same equivalence class, while using structural equivalence (binary version) only finds very small complete blocks. Two possible ways of blockmodeling such networks within a binary generalized blockmodeling approach are presented. It is also shown that sum of squares (homogeneity) generalized blockmodeling according to structural equivalence is appropriate for this task, although it suffers from \"the null block problem\". A solution to this problem is suggested that makes the approach even more suitable. All approaches are also applied to an empirical example. My general suggestion is to use either binary blockmodeling according to structural equivalence with different weights for inconsistencies or sum of squares (homogeneity) blockmodeling with null and constrained complete blocks. The second approach is more appropriate when we want complete blocks to have rows and columns of similar densities and differentiate among complete blocks based on densities. If these aspects are not important the first approach is more appropriate as it does in general produce \"cleaner\" null blocks.","PeriodicalId":242585,"journal":{"name":"Advances in Methodology and Statistics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115817556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three original samples using three different psychological test batteries served as a basis for the investigation; TEMPS-A (N = 1167), BFQ (N = 347), and ICID (N = 565). Each of these samples were then randomly split into three smaller sizes (n = 50, n = 100, n = 200), and the original sample size (N = Full) was included as well. All four sample sizes were submitted to a bootstrapping procedure with 1000 resamples with replacement, and each bootstrapped resample was analyzed with multidimensional scaling (MDS) to create two major profiles in PAMS. The resulting scale values, i.e. the coordinates from MDS, were analyzed using the bootstrapped distributions confidence intervals (CI). The smaller samples' CIs were compared towards the ones of the full sample to investigate invariance using Chebyshev's rule. The results indicate that the n = 200 samples were all invariant in comparison with the original sample sizes and produce reasonable results when the goal is to extract major profiles via bootstrapped confidence intervals using PAMS.","PeriodicalId":242585,"journal":{"name":"Advances in Methodology and Statistics","volume":"208 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132351126","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
