insight: A Unified Interface to Access Information from Model Objects in R

Abstract

When fitting any statistical model, there are many useful pieces of information that are simultaneously calculated and stored beyond coefficient estimates and general model fit statistics. Although there exist some generic functions to obtain model information and data, many package-specific modeling functions do not provide such methods to allow users to access such valuable information. insight is an R-package (R Core Team, 2019) that fills this important gap by providing a suite of functions to support almost any model (see a list of the many models supported below in the Supported Models section). The goal of insight, then, is to offer tools that provide easy, intuitive, and consistent access to information contained in model objects. These tools aid applied researchers in virtually any field who fit, diagnose, and present statistical models by streamlining access to every aspect of model objects via consistent syntax and output. Ultimately, the development of insight is in line with the philosophy of the easystats project, which is to facilitate and streamline the process of statistical analysis, interpreting and reporting the results in the R programming language.
