Returns k objects taken (aka sampled) randomly from the input array..
NxChoose(X, K, Replacement, Seed, KeepNA)
- is the input data sample (one/two dimensional array of cells (e.g. rows or columns)).
- is the number of items to draw from X. If missing, Items is assumed one(1).
- is the flag describing the draw mechanism: True=with replacement, False=without replacement (default). If missing, replacement is assumed false.
- is the seed value of the random number generator. If missing, a random number from the CPU clock is used.
- is a flag for leaving (or purging) observations with missing values (e.g. #N/A, #VALUE!, #NUM!, empty cell) found in the input data set. If missing, keepNA=False.
- The input data set may span multiple rows and/or columns, but the results is always one-dimensional array (i.e. column)..
- If the keepNA argument is set to False(0),observations with missing values (e.g. #N/A, #VALUE!, #NUM!, empty cell) in the input data set are purged prior to the choosing/sampling.
- If the replacement option is turned off, the value of the <strong>K</strong> arqument should not exceed the input data set size, otherwise NxChoose returns #N/A.
- If the keepNA argument is set to True(1), cells with missing value are preserved, and are sampled equally with other observations, and represented by #N/A in the returned array.
- The NxChoose function is available starting with version 1.66 PARSON.
