I Error in Euler angles and quaternions

Click For Summary
The discussion focuses on comparing a user's Euler angles and quaternions with corresponding sets from STK to assess accuracy. The user seeks effective metrics for measuring discrepancies, specifically inquiring about the suitability of RMSE (Root Mean Square Error) and MAD (Mean Absolute Deviation). Participants clarify the definitions of STK, RMSE, and MAD for better understanding. The conversation emphasizes the importance of selecting appropriate error metrics for accurate comparisons. Overall, the thread highlights the need for reliable methods to evaluate orientation data discrepancies.

Comparing Euler angles and quaternions from my data to STK's. Are RMSE or MAD suitable metrics for measuring discrepancies?
Hi, I got a set of Euler angles and a set of quaternions, and I wanted to compare each set against its corresponding set obtained from STK, and I was wondering what would be a good indicator to measure the error between the Euler angles I got and those from stk , and the same for quaternions, are efficient indicators like the RMSE or the MAD?

For those of us less acronym-savvy, can you please define STK, RMSE and MAD?

Thread 'Population 3 star (Pop III) candidate LAP1'

"Pop III stars are thought to be composed entirely of helium and hydrogen with trace amounts of lithium, the ingredients left over after the Big Bang. They formed early on, around 200 million years after the universe began. These stars are extremely rare because they died out long ago, although scientists have hoped that the faint light from these distant, ancient objects would be detectable. Previous Population III candidates have been ruled out because they didn't meet the three main...
