Weighting an average to minimize variance

How would you allocate money to a set of independent assets with to minimize volatility if some assets are more volatile than others?

Looking for #advice for trying to correct #ATR #FTATR #spectrum using #R / #rstudio .
I need to make my #spectra comparable to #OPTIR but I can’t figure out the #coding for #ATRcorrection 😭.

Note: I don’t need to do #baselinecorrection as such, more about #weighting :)

That'll take a while..

And might end like last time.

In 1994 Rollins Band recorded tracks with free jazz saxophonist Charles Gayle for 'Weight' and they weren't able to include them. In 2004, 'Weighting' was released with the tracks & they're FIRE. All worth hearing, this might be my favorite. Over TWELVE MINUTES LONG, it's a fucking masterpiece of jazz and Rollins' spoken word 🔥

The last time that the #marketcap #weighting grossly exceeded #earnings, it didn't end well. The question this time is whether earnings can catch up with current expectations.

This new method provides a framework for how to best understand a collection of climate models. The model weights included in this research informed the Fifth National Climate Assessment, a report released on Nov. 14 that gauges the impacts of climate change in the United States. This project also supports the Earth System Grid Federation, an international collaboration led in the U.S. by DOE that manages and provides access to climate models and observed data…”

Scientists combine climate models for more accurate projections

Researchers from institutions including the Department of Energy's Oak Ridge National Laboratory have created a new method for statistically analyzing climate models that projects future conditions with more fidelity.
