PharmPK Discussion - How to handle Missing data in Phoenix WinNonlin

  Hello
  I have a query on how do we handle missing data in Phoenix WinNonlin, In
  WNL 5.2  we had an explicit option of converting missing values with
  "."(dot) using Workbook edit option, whereas in PHX WNL we don't have
  any such option of editing
  I would be happy if anybody can help me in understanding how to handle
  the missing values in PHX WNL
  
  Regards
  Kaushik

  Hi Kaushik,
  You can use the "Data Wizard" option for all data manipulations, which
  is located in data.
  Hope this helps.
  Thanks,
  Soujanya

  Hi Harish,
   As you've asked the question here also I'm including the link to my
  response on the Phoenix user forum for others who might want to know and
  discuss usage.

  Kaushik, Phoenix has no explicit missing data value. If a numeric cell
  is empty then it is treated as missing.
  
   If you perform numerical operations on a column containing both numbers
  and text then those cells which are not numbers are all treated as
  missing.  The advantage of this that I see is you can simply use your
  data as it came from the lab, NS, BLQ,  <10, all of these will be
  treated as missing in graphs, NCA, Desc. Stats etc. but if listed in a
  table the original value is still reported.
  
         Best regards,
                          Simon.

  Hi Kaushik,
  
  Maybe you can directly input "Missing" to the raw data and then guide
  the data into Phoenix WinNonlin, the system can not identify  "Missing"
  values, and this data (this time point) will be excluded when
  calculating parameters.
  
  Thanks,
  Han
