csv.covariate_both¶

Add both Sex to csv Covariate Table¶

Prototype¶

# at_cascade.csv.covariate_both
def covariate_both(covariate_table_in) :
   assert type(covariate_table_in) == list
   for row in covariate_table_in :
      for key in row :
         type_check = str if key in [ 'node_name' , 'sex' ] else float
         assert type( row[key] ) == type_check
   #
   assert type(covariate_table_out) == list
   for row in covariate_table_out :
      for key in row :
         type_check = str if key in [ 'node_name' , 'sex' ] else float
         assert type( row[key] ) == type_check
   return covariate_table_out

covariate_table_in¶

Is a list of dict representation of a covariate.csv file.

covariate_table_out¶

Is a list of dict representation of covariate.csv file. This has all the rows that are in covariate_table_in plus rows with sex equal to both .

both¶

For each node_name, age, time, the covariate table value for sex equal both is the average of its value for female and male . To be specific, if female_value, male_value, both_value are a covariate’s values for a specific (node_name, age, time) then:

   if female_value == male_value :
      both_value = female_value
   else :
      both_value = ( float( female_value ) + float( male_value ) ) / 2.0
