p0 |
matrix of joint probabilities. Default is

p0_v1,p0_v2 |
probablity of no precipitatin occurences for the v1 and v2 time series respectively. |

both v1 and v2 simultanously returned by

tolerance (numeric) parameter used for comparisons with the extreme value of marginal probabilities. Default is 0.001. |

input argument
of omega
.
This function find the zero of the omega_root
function by calling uniroot
. If the argument
p0
is not NULL
and is a matrix of joint
probabilities, the function returns a correlation matrix by
using the elements of p0
ass joint probabilities for
each couple and p0_v1
as a vector of marginal
probability of each occurence/no-occurence (In this case if
the length of p0_v1
does not correspond to the
number of columns of p0
, the marginal probabilities
are taken from the diagonal of p0
). See the R code
