The STDIZE Procedure |
Task | Options | Description |
Specify standardization methods | METHOD= | specifies the name of the standardization method |
INITIAL= | specifies the method for computing initial estimates for the A estimates | |
Unstandardize variables | UNSTD | unstandardizes variables when you also specify the METHOD=IN option |
Process missing values | NOMISS | omits observations with any missing values from computation |
MISSING= | specifies the method or a numeric value for replacing missing values | |
REPLACE | replaces missing data by zero in the standardized data | |
REPONLY | replaces missing data by the location measure (does not standardize the data) | |
Specify data set details | DATA= | specifies the input data set |
OUT= | specifies the output data set | |
OUTSTAT= | specifies the output statistic data set | |
Specify computational settings | VARDEF= | specifies the variances divisor |
NMARKERS= | specifies the number of markers when you also specify PCTLMTD=ONEPASS | |
MULT= | specifies the constant to multiply each value by after standardizing | |
ADD= | specifies the constant to add to each value after standardizing and multiplying by the value specified in the MULT= option | |
FUZZ= | specifies the relative fuzz factor for writing the output | |
Specify percentiles | PCTLDEF= | specifies the definition of percentiles when you also specify the PCTLMTD=ORD_STAT option |
PCTLMTD= | specifies the method used to estimate percentiles | |
PCTLPTS= | writes observations containing percentiles to the data set specified in the OUTSTAT= option | |
Normalize scale estimators | NORM | normalizes the scale estimator to be consistent for the standard deviation of a normal distribution |
SNORM | normalizes the scale estimator to have an expectation of approximately 1 for a standard normal distribution | |
Specify output | PSTAT | displays the location and scale measures |
Value | Divisor | Formula |
DF | degrees of freedom | n-1 |
N | number of observations | n |
WDF | sum of weights minus 1 | ( |
WEIGHT | WGT | sum of weights |
