It’s almost too good to be true… but you can map an empirical correlation matrix into approximately uncorrelated and standardized variables. The generalized Fisher transform makes this possible. Link to latest draft of working paper with Ilya Archakov. #GFT #Econometrics

Ser kommentarer som ser dette som tegn på doping, og jeg undrede mig også sidste år, hvor Vingegaard og Pogacar begge havde præstationer på Armstrong/Riss niveau. Men der har været forbedringer af grej og hypoxic training som delvist (og lovligt) giver samme effect som EPO. #LivingHighTrainingLow

At bruge råderummet er lidt som at bygge en carport. Det er ikke sikkert, det er en god forretning
I disse år bliver det økonomiske råderum igen og igen opjusteret. Hvad skal vi bruge pengene på? Det kan være, at det i virkeligheden ikke er det helt rigtige spørgsmål at stille.
