This function finds the bivariate joint probability or the binary correlation from the corresponding Gaussian correlation x
Description
This function finds the bivariate joint probability or the
binary correlation from the corresponding Gaussian
correlation x
Usage
1 
Arguments
x 
value of expected correlation between the corresponding Gaussiandistributed variables 
p0_v1,p0_v2 
probability of no precipitation
occurences for the v1 and v2 time series respectively.
See 
correlation 
logical numeric value. Default is

Value
probability of no precipitation occurence in both v1 and v2
simultaneously. It is a matrix if x
is a matrix.
Note
This function makes use of normal copula. A graphical
introduction to this function (with its inverse) makes is
present in the following URL references:

(See fig. 1 and par. 3.2) If the argument p0_v2
, the
two marginal probabily values must be given as a vector
through the argument p0_v1
:
p0_v1=c(p0_v1,p0_v2)
. In case x
is a
correlation/covariance matrix the marginal probabilities
are given as a vector through the argument p0_v1
.
