HyetosRepScheme {HyetosMinute} | R Documentation |
The function HyetosRepScheme
disaggregates daily rainfall into hourly or sub-hourly rainfall. It is the main subroutine of DisagSimul.test
and DisagSimul
functions.
HyetosRepScheme(L,l,f,k,a,v,mx,sxmx,WeiTF,iOTA,Zhist, da,F,MinNumLevel1Rep,TotalNumRep,timescale)
L |
A positive integer that specifies the number of wet days followed by one or more dry days. |
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 |
Shape parameter of gamma distribution |
v |
Scale parameter 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. |
WeiTF |
Logical value that specifies if the intensities follow the Weibull distribution. |
iOTA |
Ratio ι=μ_x/η for the case of Bartlett-Lewis model with dependent intensity-duration, NA otherwise. |
Zhist |
Vector of the original daily depths of the wet days sequence. |
da |
A positive number that specifies the distance used to judge whether synthetic daily depths resemble the real ones. Default value is |
F |
A positive number that specifies the factor for Level 1 repetitions allowed. Default value is |
MinNumLevel1Rep |
A positive integer that specifies the minimum number of Level 1 repetitions allowed. Default value is |
TotalNumRep |
A positive integer that specifies the total repetitions allowed. Default value is |
timescale |
The time scale of disaggregated data (number) (e.g. 1/60 for 1 min, 1/30 for 2min, 1/12 for 5 min). |
u |
Matrix of adjusted hourly rainfall depths of |
