omega_root {RGENERATEPREC} | R Documentation |
This is the target function whose zero is searched to crete the inverse function of omega
.
Description
This is the target function whose zero is searched to crete the inverse function of omega
.
Usage
omega_root(
x = 0.5,
p0_v1 = 0.5,
p0_v2 = 0.5,
p00 = p0_v1 * p0_v2,
correlation = NA
)
Arguments
x |
value of expected correlation between the corresponding Gaussian-distributed variables |
p0_v1 , p0_v2 |
probablity of no precipitatin occurrences for the v1 and v2 time series respectively. |
p00 |
probability of no precipitation occurrence in both v1 and v2 simultanously returned by |
correlation |
numerical value. DEfault is |
Value
the value p00-omega(x=x,p0_v1=p0_v1,p0_v2=p0_v2)
or correlation-omega(x=x,p0_v1=p0_v1,p0_v2=p0_v2)
(if correlation
is not NA
)
Note
This function makes use of normal copula
