@data @datadon 🧵

How to assess a statistical model?
How to choose between variables?

Pearson's #correlation is irrelevant if you suspect that the relationship is not a straight line.

If monotonic relationship:
"#Spearman’s rho is particularly useful for small samples where weak correlations are expected, as it can detect subtle monotonic trends." It is "widespread across disciplines where the measurement precision is not guaranteed".
"#Kendall’s Tau-b is less affected [than Spearman’s rho] by outliers in the data, making it a robust option for datasets with extreme values."

#Pearson #correlation is excellent to identify outliers, as a single large value can shift the result quite dramatically.

The associated image comes from a published panel figure of a scientific paper (2020). I would refrain, however, to consider that the observed correlation has biological significance... or that it is really a correlation...

>> One of interim Iranian President Mohammad #mokhber first phone calls since ascending to the position was with the #kremlin. In October 2022, Mokhaber went to #Moscow to sell #Iraniandrones and #ballisticmissiles to #Russia

Now, I know that everyone who confuses #correlation and #causation ends up dying.

Still note correlation in timing of #Putin’s #China visit and #Raisi helicopter crash.

@ekmiller May be, may be not. But keep on playing!
Conclusion:
We show that playing a musical instrument during life relates to higher RSFC of the medial prefrontal cortex with distant brain regions involved in higher-order cognitive and motor processes. Preserved or enhanced functional connectivity could potentially contribute to better brain health and resilience in OA with a history in musical activity.
