Nuovi Decessi e Terapie Intensive

Correlazione tra nuovi deceduti e terapie intensive.

Max Pierini

Rapporto grezzo nuovi deceduti su terapie intensive:

Definizione e rimozione outliers (minori di 0% e maggiori di 100%)

2020-06-24 00:00:00: -28.97%
2020-08-15 00:00:00: 287.27%

Fit su polinomio di ottavo grado

Correlazione sulla linea temporale.

Per ovviare alla eteroschedasticità la correlazione sarà effettuata sul logaritmo

$$ \ln(\textrm{nuovi_deceduti}) = \alpha + \beta \cdot \ln(\textrm{terapia_intensiva}) $$
