Joinpoint allows the independent variable to be renamed, its values to be recoded, and display labels assigned to each value. If the variable is recoded, the recoded values are used in the Joinpoint calculations.
The following attributes can be set for the Independent variable:
Variable name:
The name must be of reasonable length and it is recommended that the label be concise (short) for ease of viewing in the output.
Independent Variable Coding Information (Value = Recode (Calculation value) = Display Label):
An example of an Independent Variable format would be:
Variable Name: Year of Diagnosis - 1993-2013
Value |
Value Used In Calculation |
Use Custom Display Labels |
|
0 |
1993 |
Ninety Three |
|
1 |
1994 |
Ninety Four |
|
2 |
1995 |
Ninety Five |
|
Etc. |
Recode/Calculation values MUST be numeric. Recode values and Display Labels must also be a reasonable length and it is recommended they be concise for ease of viewing in the output.
When using a SEER*Stat dictionary file (*.DIC), any independent variable value with a dash (*-*) located in its format label will not be used in the analysis. The label will be updated to contain the following text: “not used in calculations”. This functionality was added so that users would not have to reproduce their SEER*Stat analyses in order to remove totals or sub-totals in their independent variable.
