Afifi and Azen Data Set A |
Set IDATA = 0 to print a description of all the data sets above. In this case, the remaining arguments are not referenced.
X — NOBS by NVAR matrix containing the data set. (Output)
NOBS — Number of observations or rows in the output matrix. (Output)
NVAR — Number of variables or columns in the output matrix. (Output)
IPRINT — Printing
option. (Input)
Default: IPRINT = 0.
IPRINT Action
0 No printing is performed.
1 Rows 1 through 10 of X are printed.
2 All rows of X are printed.
When printing is performed, a header listing the data set name and a reference is printed.
LDX — Leading
dimension of X
exactly as specified in the dimension statement in the calling program.
(Input)
Default: LDX = size (X,1).
NDX — Second
dimension of the matrix X exactly as specified
in the dimension statement of the calling program.
(Input)
Default: NDX = size (X,2).
Generic: CALL GDATA (IDATA, X, NOBS, NVAR,[,…])
Specific: The specific interface names are S_GDATA and D_GDATA.
Single: CALL GDATA (IDATA, IPRINT, NOBS, NVAR, X, LDX, NDX)
Double: The double precision name is DGDATA.
Routine GDATA retrieves a standard data set frequently cited in statistics textbooks or in this manual. The following table gives the references for each data set:
