vslSSEditPooledCovariance

Modifies pooled/group covariance matrix array pointers.

Syntax

status = vslssseditpooledcovariance(task, grp_indices, pld_mean, pld_cov, req_grp_indices, grp_means, grp_cov)

status = vsldsseditpooledcovariance(task, grp_indices, pld_mean, pld_cov, req_grp_indices, grp_means, grp_cov)

Description

task

Fortran: TYPE(VSL_SS_TASK)

Descriptor of the task

grp_indices

Fortran: INTEGER DIMENSION(*)

Pointer to an array of size n. The i-th element of the array contains the number of the group the observation belongs to.

pld_mean

Fortran: REAL(KIND=4) DIMENSION(*) for vslssseditpooledcovariance

REAL(KIND=8) DIMENSION(*) for vsldsseditpooledcovariance

Pointer to the array of pooled means

pld_cov

Fortran: REAL(KIND=4) DIMENSION(*) for vslssseditpooledcovariance

REAL(KIND=8) DIMENSION(*) for vsldsseditpooledcovariance

Pointer to the array that holds a pooled covariance matrix

req_grp_indices

Fortran: INTEGER DIMENSION(*)

Pointer to the array that contains indices of groups for which estimates to return (such as covariance and mean)

grp_means

Fortran: REAL(KIND=4) DIMENSION(*) for product=Fortran vslssseditpooledcovariance

REAL(KIND=8) DIMENSION(*) for vsldsseditpooledcovariance

Pointer to the array of group means

grp_cov

Fortran: REAL(KIND=4) DIMENSION(*) for vslssseditpooledcovariance

REAL(KIND=8) DIMENSION(*) for vsldsseditpooledcovariance

Pointer to the array that holds group covariance matrices

Output Parameters

status

Fortran: INTEGER

Current status of the task

Description

The vslSSEditPooledCovariance routine replaces pointers to the array of group indices, the array of pooled means, the array for a pooled covariance matrix, and pointers to the array of indices of group matrices, the array of group means, and the array for group covariance matrices with values passed in the editors. If you pass a value of NULL for a specific input parameter, the value of that parameter in the task descriptor is unchanged.. Use the vslSSEditTask routine to replace the storage format for pooled and group covariance matrices.
