Distribuzioni continue
Usa la migliore distribuzione continua per i dati.
- Crea un istogramma
- Prova funzioni continue, adattandole all’istogramma.
- Tieni quella con l’errore minore rispetto all’istogramma.
Distribuzione continua
Applicare una distribuzione
import scipy.stats# Fit the genlogistic distribution to the continuous variable Age params = scipy.stats.genlogistic.fit(hr['Age'])# See the parameters of the continuous functions print(params)
(4.9899067653418285, 22.32808853181744, 7.046590524738551)
Campionare da una distribuzione continua
# Sample from the genlogistic distribution df['Age'] = scipy.stats.genlogistic.rvs(size=len(df.index), *params)# See the resulting dataset df['Age'].head()
