ModelledStats {HyetosMinute} | R Documentation |
The function ModelledStats
is used to calculate and print the modelled statistics of rainfall depth according to the equation of Bartlett-Lewis rectangular pulse model.
ModelledStats(a,l,v,k,f,mx,sxmx,h,iota,TFweib)
l |
A positive number that specifies the rate of Poisson process. The time units are days (d). |
f |
Constant φ=γ/η. |
k |
Constant κ=β/η. |
a |
A positive number that specifies the shape parameter α of gamma distribution. |
v |
A positive number that specifies the scale parameter ν of gamma distribution. |
mx |
A positive number that specifies the mean of cell intensities. |
sxmx |
A positive number that specifies the ratio of standard deviation to mean cell intensity. |
h |
The time scale of data. |
iota |
Ratio ι=μ_x/η for the case of Bartlett-Lewis model with dependent intensity-duration, NA otherwise. |
TFweib |
Logical value that specifies if the intensities follow the Weibull distribution. |
t |
A matrix that contains the modelled statistics of rainfall depth. |
