Min-Max Data Filtering

This node computes and creates a new output data spreadsheet that has been filtered through a list of min-max limits. Data values outside the min-max limits can be set to missing data, to the user-specified min or max values, 25th and 75th percentile values, means, medians, or the respective cases can be discarded altogether. For each type of variable, and optionally range of variables, the user can specify the minimum and maximum values that are valid for each variable specified in the input description. Note:
 (1) If a variable contains text values, the minimum and maximum are referenced to the numerical values (equivalents) for those text values (see also help topic: text values).
 (2) Any pre-existing case selection conditions in the input data source (file) will first be applied before any subsequent filtering.
 (3) All boundary values for filtering (min, max) are inclusive, i.e., the valid data range is Min<=x<=Max.
 (4) If case selection conditions are in effect, these will be applied to the computation of means, medians, etc.

Element Name Description
Type of filtering Type of filtering to be performed; out-of-range values can be replaced with missing data codes, with the user-specified Min or Max values, estimated quartiles, medians, means, or cases with out-of-range values can be discarded altogether. If case selection conditions are in effect, these will be applied to the computation of means, medians, etc.
Dependent; Continuous Min Minimum range value for continuous dependent variables. Note: All boundary values for filtering (min, max) are inclusive, i.e., the valid data range is Min<=x<=Max.
Dependent; Continuous Max Maximum range value for continuous dependent variables. Note: All boundary values for filtering (min, max) are inclusive, i.e., the valid data range is Min<=x<=Max.
Apply filter to Specifies whether to apply the filtering (min/max checking) to a specified subset list of variables only (within this list of continuous dependent variables).
Subset of variables; from This option is only applicable if the filtering is to be applied to selected variables only. Specify the first variable in the range of variables in the list of continuous dependent variables to which to apply the min/max filtering. Specify a number that will be interpreted as the index to the list of continuous dependent variables; for example, if you specified '3', then the filtering will be applied starting with the third variable in the list of continuous dependent variables (and not with variable number 3 in the original data file).
Subset of variables; to This option is only applicable if the filtering is to be applied to selected variables only. Specify the last variable in the range of variables in the list of continuous dependent variables to which to apply the min/max filtering. Specify a number that will be interpreted as the index to the list of continuous dependent variables; for example, if you specified '3', then the filtering will be applied up to the third variable in the list of dependent variables (and not up to variable number 3 in the original data file).

Element Name Description
Subset variables downstream This node will create a data spreadsheet for further subsequent analyses. You can either create a subset of the variables, retaining only those that were selected for the analyses (select Yes), or you can 'carry along' all variables from the original input data source.
