Hello everyone,
I was trying to do some distribution fitting with a numerical field called
Tolls. The sample size = 999 rows.
Basically I assigned the Toll data to a new variable K by doing:
k<-dtest$Toll
After that, tried to fit a gamma distribution by doing: fitG<-fitdist(k,
"gamma")
Then the following messages showed (oh and I checked for empty rows before
doing this):
Warning in dgamma(c(363328L, 376216L, 367032L, 314826L, 311892L, 313340L, :
