SpecialDataCodes

public SpecialDataCodes()

SpecialDataCodes

public SpecialDataCodes(java.lang.String codeString)

Creates an object using the variable name and code string. The code string if formatted like (NA,OM,NR)(-1,-1,-1)

Parameters:

codeString -

Method Detail

parseSpecialCodeString

public void parseSpecialCodeString(java.lang.String codeString)

Parses the code string that has the format (NA,OM,NR)(-1,-1,-1). The comma separated values in the first set of parentheses are the special data codes for missing, omitted, and not reached responses, respectively. The comma separated list in the second set of parentheses are the points assigned to each code. A score of -1 indicates that the response should be ignored. Typically, the score will either be -1 (ignore) or 0 (score as zero points).

Parameters:

codeString -

setMissingDataCode

public void setMissingDataCode(java.lang.Object missingDataCode)

setOmittedCode

public void setOmittedCode(java.lang.Object omittedCode)

setNotReachedCode

public void setNotReachedCode(java.lang.Object notReachedCode)

setMissingDataScore

public void setMissingDataScore(double missingDataScore)

setOmittedScore

public void setOmittedScore(double omittedScore)

setNotReachedScore

public void setNotReachedScore(double notReachedScore)

getMissingDataCode

getOmittedCode

public java.lang.Object getOmittedCode()

getNotReachedCode

public java.lang.Object getNotReachedCode()

isMissing

public boolean isMissing(java.lang.String response)

isMissing

public boolean isMissing(java.lang.Object object)

isMissing

public boolean isMissing(double response)

isMissing

public boolean isMissing(int response)

isOmitted

public boolean isOmitted(java.lang.Object response)

isNotReached

public boolean isNotReached(java.lang.Object response)

computeMissingScore

public double computeMissingScore(java.lang.String response)

Computes the score associated with a missing data code. If no matching code is found then it returns -1. You should check for missing data with isMissing() before calling this method. Otherwise, calculation errors may occur because -1 returned when a different (nonmissing) value should be returned.

Parameters:

response -

Returns:

computeMissingScore

public double computeMissingScore(java.lang.Object response)

computeMissingScore

public double computeMissingScore(double response)

computeMissingScore

public double computeMissingScore(int response)

toString

public java.lang.String toString()

Prints the code string.

Overrides:

toString in class java.lang.Object

Returns:
