Degrees of freedom are important to the understanding of model fit if for no other reason than that, all else being equal, the fewer degrees of freedom, the better indices such as χ 2 will be. It has been shown that degrees of freedom can be used by readers of papers that contain SEMs to determine if the authors of those papers are in fact ...

This article is a list of freedom indices produced by several non-governmental organizations that publish and maintain assessments of the state of freedom in the world, according to their own various definitions of the term, and rank countries using various measures of freedom, including ...
Economic Freedom of the World is an annual survey published by the Fraser Institute, a Canadian think tank. [1] The survey attempts to measure the degree of economic freedom in the world's nations. It has been used in peer-reviewed studies, some of which have found a range of beneficial effects of more economic freedom. [2]
Between 1995, the first edition of the Index, and 2008, the score for world economic freedom has increased, rising 2.6 points, according to the Index. [10] Between 2008 and 2011, however, the score decreased 60.2 to 59.7, though the 2011 score represents an increase of 2.2 points since the first edition in 1995.

By 2020, the V-Dem index had "more than 470 indicators, 82 mid-level indices, and 5 high-level indices covering 202 polities from the period of 1789–2019". [2] V-Dem uses methodological tools to deal with the subject nature of ratings and their reliability.
Democracy indices are quantitative and comparative assessments of the state of democracy [1] for different countries according to various definitions of democracy. [2]The democracy indices differ in whether they are categorical, such as classifying countries into democracies, hybrid regimes, and autocracies, [3] [4] or continuous values. [5]
The degrees of freedom are not based on the number of observations as with a Student's t or F-distribution. For example, if testing for a fair, six-sided die, there would be five degrees of freedom because there are six categories or parameters (each number); the number of times the die is rolled does not influence the number of degrees of freedom.
