Public Sector Credit Framework : ウィキペディア英語版 | Public Sector Credit Framework The Public Sector Credit Framework is an open source tool for estimating the default risk of and assigning ratings to government debt. The PSCF installation package was released on May 2, 2012.〔(【引用サイトリンク】title=Public Sector Credit Framework )〕 At the same time, source code was published on GitHub.〔(【引用サイトリンク】title=github )〕 The publishers, PF2 Securities Evaluations and Public Sector Credit Solutions, said that they released the software in response to the need for "transparent, objective and up-to-date government credit ratings."〔("Public Sector Credit Framework Download Page" )〕 The project has similar goals to an earlier mass collaboration bond rating effort, Wikirating. ==Description== PSCF calculates government default probabilities through the use of a multi-year fiscal simulation and a default point, expressed in terms of a user-specified financial ratio. The proportion of simulation trials surpassing the default point represents the default probability for a given year. The simulation is typically created in an Excel worksheet. Each row of the worksheet represents a different user specified series. Series may contain random numbers, macroeconomic variables, revenues, expenditures and debt levels. In a typical simulation, random numbers are listed first, then macroeconomic variables are specified as functions of the random variables (as well as constants and previous levels of the macroeconomic variable). Revenues and expenditures can then be expressed as functions of the macroeconomic variables.
