However, its computational efficiency depends on the choice of regularization parameter (tuning parameter), and selecting this parameter can be highly time consuming. Although fully Bayesian implementations of Glasso alleviate this problem somewhat by specifying a priori distribution for the parameter, these approaches lack the scalability of their frequentist counterparts.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Here, we present a new Monte Carlo Penalty Selection method (MCPeSe), a computationally efficient approach to regularization parameter selection for Glasso. MCPeSe combines the scalability and low computational cost of the frequentist Glasso with the ability to automatically choose the regularization by Bayesian Glasso modeling. MCPeSe provides a state-of-the-art \u2018tuning-free\u2019 model selection criterion for Glasso and allows exploration of the posterior probability distribution of the tuning parameter.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Availability and implementation<\/jats:title>\n                  <jats:p>R source code of MCPeSe, a step by step example showing how to apply MCPeSe and a collection of scripts used to prepare the material in this article are publicly available at GitHub under GPL (https:\/\/github.com\/markkukuismin\/MCPeSe\/).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Supplementary information<\/jats:title>\n                  <jats:p>Supplementary data are available at Bioinformatics online.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/bioinformatics\/btaa734","type":"journal-article","created":{"date-parts":[[2020,8,12]],"date-time":"2020-08-12T19:32:50Z","timestamp":1597260770000},"page":"726-727","source":"Crossref","is-referenced-by-count":7,"title":["MCPeSe: Monte Carlo penalty selection for graphical lasso"],"prefix":"10.1093","volume":"37","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9074-7420","authenticated-orcid":false,"given":"Markku","family":"Kuismin","sequence":"first","affiliation":[{"name":"Research Unit of Mathematical Sciences, University of Oulu , Oulu FI-90014, Finland"},{"name":"Biocenter Oulu, University of Oulu , Oulu FI-90014, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2808-2768","authenticated-orcid":false,"given":"Mikko J","family":"Sillanp\u00e4\u00e4","sequence":"additional","affiliation":[{"name":"Research Unit of Mathematical Sciences, University of Oulu , Oulu FI-90014, Finland"},{"name":"Biocenter Oulu, University of Oulu , Oulu FI-90014, Finland"},{"name":"Infotech Oulu, University of Oulu , Oulu FI-90014, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2020,8,17]]},"reference":[{"key":"2023051704100590600_btaa734-B1","first-page":"485","article-title":"Model selection through sparse maximum likelihood estimation for multivariate Gaussian or binary data","volume":"9","author":"Banerjee","year":"2008","journal-title":"J.
