Currently, this estimation concerns that\nof various Gaussian graphical models from different study\ndesigns. Among others it considers the regular Gaussian\ngraphical model and a mixture of such models. The\nporridge-package implements the estimation of the former either\nfrom i) data with replicated observations by penalized\nloglikelihood maximization using the regular ridge penalty on\nthe parameters (van Wieringen, Chen, 2021) or ii) from\nnon-replicated data by means of either a ridge estimator with\nmultiple shrinkage targets (as presented in van Wieringen et\nal. 2020, ) or the generalized\nridge estimator that allows for both the inclusion of\nquantitative and qualitative prior information on the precision\nmatrix via element-wise penalization and shrinkage (van\nWieringen, 2019, ).\nAdditionally, the porridge-package facilitates the ridge\npenalized estimation of a mixture of Gaussian graphical models\n(Aflakparast et al., 2018). On another note, the package also\nincludes functionality for ridge-type estimation of the\ngeneralized linear model (as presented in van Wieringen,\nBinder, 2022, ).", "License": "GPL (>= 2)",
