xexp

indices 
( 
Secondary function of the package that calculates a number of sampling related variables and diversity estimators for each bin.
In contrast to the (divDyn
) function, the bins are treated independently in this function.
The function also returns the maximum subsampling quota for OxW subsampling
(subtrialOXW
) with a given xexp
value.
By setting total
to FALSE
(default), the following results are output:
occs
: The number of occurrences in each time bin.
colls
: The number of collections in each time bin.
xQuota
: The maximum quota for OxW subsampling (subtrialOXW
) with the given xexp
value.
The number of occurrences in each collection is tabulated, and is raised to the power of xexp
.
The xQuota
value is the sum of these values across all collections in a time slice.
refs
: The number of references in each time bin.
SIBs
: The number of SampledInBin taxa in each time bin.
occ1
: The number of taxa in each time bin, that occur in only 1 collection.
ref1
: The number of taxa in each time bin, that occur in only 1 reference.
occ2
: The number of taxa in each time bin, that occur in exactly 2 collections.
ref2
: The number of taxa in each time bin, that occur in exactly 2 references.
u
: Good's u, coverage estimator based on the number of singlecollection taxa (occ1).
uPrime
: Good's u, coverage estimator based on the number of singlereference taxa (ref1).
chao1occ
: Chao1 extrapolation estimator, based on the the number of singlecollection and twocollection taxa (occ1).
chao1ref
: Chao1 extrapolation estimator, based on the the number of singlereference and tworeference taxa (occ2).
