Relationship between the Inverse-Gamma and Scaled-Inverse-Chi-Square

I came across the following passage in Gelman's Bayesian Data Analysis (chapter 2): A convenient parameterization [of the inverse-gamma conjugate prior for a normal distribution with known mean and unknown variance] is the scaled inverse-chi-square distribution with scale $\sigma^{2}_0$ and $\nu_0$ degrees of freedom; that is, the prior distribution of $\sigma^{2}$ is taken to be the distribution of $\sigma^{2}_0/X$ , where $X$ is a $\chi^{2}_{\nu_0}$ random variable. We use the convenient but nonstandard notation, $\sigma^2 \sim Inv-\chi^2(\nu_0,\sigma^{2}_0)$ . Gelman goes on show the resulting posterior density for $\sigma^2_0$ based on the above relationship between the inverse-gamma and scaled inverse-chi-square. Besides their shared distribution form, what's the intuitive reason or relationship for parameterizing the inverse-gamma with the scaled inverse-chi-square here? Is it that the scaled inverse-chi-square's parameters are more closely linked to the data sample $y_1,...,y_n$ and the posterior parameter of interest, $\sigma^2$ ?

Microsoft rolls out .NET 11 Preview 7

Microsoft has announced the seventh preview release of the .NET 11 open source developer platform, with improvements ranging from tiered compilation for async methods and a milestone in bringing CoreCLR to WebAssembly . Developers can download Preview 7 from dotnet.microsoft.com . Production availability for .NET 11 is expected in November. Unveiled August 11 , .NET 11 Preview 7 includes improvements across libraries, the .NET runtime, SDK, C# , ASP.NET Core, .NET MAUI, Entity Framework Core, F#, and Windows Forms, according to Microsoft. With this latest preview, runtime-async — the runtime’s built-in implementation of async / await — continues to close the gap with the compiler-generated state-machine model, according to Microsoft. Async versions of methods are now compiled through the tiered compilation pipeline. Async methods previously bypassed tiering and always ran the tier0 code, which was optimized for compilation speed rather than steady-state throughput. On the WebAssembly front, .NET 11 is bringing CoreCLR to WebAssembly with a portable interpreter-plus-R2R (ReadyToRun) model that reuses RyuJIT for ahead-of-time code generation. This configuration could start up in Preview 6, and now runs the CoreCLR libraries test suite end-to-end in Preview 7. Preview 7 also brings C# language and compiler updates including labeled break and continue . With C# 15, break and continue can name an enclosing loop or switch , allowing developers to exit or continue an outer construc…

Quoting Florian Herrengt

But then users start to report a weird bug. It's the 4th time your team has been trying to fix it. I mean... asking AI to fix it. Unfortunately, it seems like not even Fable can figure it out. You go talk to the person who worked on this feature. "So where does the data come from?" "Hmm... actually I don't know. Let me ask Claude." You sit next to each other watching an endless wall of text appear on the screen. Neither of you has any idea whether any of it is true but Claude seems very confident. [...] This project has become so convoluted, with so many layers and services, that no one on your team could possibly start to understand what's going on. — Florian Herrengt , AI is removing the middle class of software engineering Tags: ai-misuse , cognitive-debt , generative-ai , ai , llms , ai-assisted-programming

How to Use AI Agents in IntelliJ IDEA With ACP

The Agent Client Protocol (ACP) defines a common contract between a client – like IntelliJ IDEA – and an agent. IntelliJ IDEA already includes several ACP-compatible agents: Codex, Claude Agent, and Junie. Beyond these bundled options, the ACP Registry provides more choices, and teams can register internal or unlisted agents through acp.json. The key idea […]
