myCSG © |Area: ADaM| Concept: C1004 : ADaM BDS Derived Parameters Creation | Lesson: L102 : Creation of a New Parameter to Handle a Second System of Units (Height in both cm and m) |

  • We have height of the subjects collected in centimeters
  • For analysis purposes, let us assume that we need to report the height in meters as well 
  • So, we are creating a new set of rows with a different parameter name to store the converted values

 

Height (cm)

Height (cm)      
Height (cm)      
Height (m)      
Height (m)      
Height (m)      
Height (m)      
VARIABLE_NAMEVARIABLE_LABELDERIVATION
ADT Analysis Date 1. Derive this variable using VS.VSDTC
2. Extract the date portion from VSDTC and convert it to numeric value.
PARAM Parameter A. For source parameters:
1. Derive this variable using VS.VSTEST and VS.VSSTRESU
2. When VSTESTCD in ('HEIGHT') then set PARAM as VSTEST||" ("||VSTRESU||")"
B. Create a derived paramter 'Height (m)' using the source parameter 'Height (cm)'.
PARAMCD Parameter Code A. For the source parameters, set to VS.VSTESTCD
B. For the derived paramter 'Height (m)' set to 'HEIGHTMT'
AVAL Analysis Value A. For the source parameters set to VS.VSSTRESN
B. For the derived parameter 'Height (m)':
1. Set AVAL to (AVAl/100) where PARAMCD="HEIGHT"
2. Round the AVAL to two decimals
