funs.vartct | R Documentation |
Three functions: var.tctI
, var.tctIII
and var.tctIV
.
These functions return the variances of T_{ij} values for i,j=1,…,k in the TCT in matrix form which
is of the same dimension as TCT for types I, III and IV tests.
The argument covN
must be the covariance between N_{ij} values which are obtained from the NNCT by row-wise
vectorization.
These variances are valid under RL or conditional on Q and R under CSR.

ct |
A nearest neighbor contingency table |
covN |
The k^2 \times k^2 covariance matrix of row-wise vectorized cell counts of NNCT, |
Each of these functions returns a matrix
of same dimension as, ct
, whose entries are the variances of
the entries in the TCT for the corresponding type of cell-specific test.
The row and column names are inherited from ct
.
