#statstab #464 Should a pilot study change your study design decisions?

Thoughts: You shouldn't use the ES, but you can use the SD (see also #192) for planning.

Simulating data for Dirichlet regression with varying estimates Hello everyone, The shortest formulation of my problem is the following: I’m trying to design a power analysis by simulation for a Dirichlet regression model using brms. How could we calculate the s...

White America, not the DSA, held the power to secure Harris. That’s where the abandonment happened. Everything else is deflection. #USPolitics #PowerAnalysis

Brookings: DSA ≈ 78,000 people in a nation of 168M voters.

Meaning: Even full unity inside the DSA cannot move a presidential outcome.

AI ethics debates are a distraction. The real fight is between governments trying to control models, and corporations trying to control governments.

Understanding Power Analysis & Estimation: 2 Recommended Readings As SoCs are getting more complex, power becomes just as important as functionality correctness or performance. This article, “Unified Methodology for Effective Correlation of SoC Power Estimation and Signoff" by Infineon Technologies, addresses the growing challenges in accurately estimating and correlating power in complex SoCs. This article is a good start to understand how the ASIC industry handles power concerns intelligently and early.

In this post, we recommend two readings to help people better understanding how power analysis flow works and how power estimation is done. Check this out!
