Hi,
I am trying to calculate Infant mortality and even though I've the Guide a thousand time I seem to be missing something, because my results do not match the final report:
I am using R code, but it's really not about the code, but about the understanding of how to define the cohorts, the nominator and the denominator:
##Variables I use:
#b3:date of birth in CMC
#b5: Child Alive? yes=1, no=0
#b7:age at death in month
#b13=flag for age of death
#sweights = sample weights
#v008 date of interview
#v024:state id's
#Reference Period:
Reference Period:Five years (60 month) before survey/interview->upper limit(tu=v008-1) ; lower limit(tl=v008-1-60)
#Cohortes (as an example age segment=0 month & 1-2 month)
cohort_a_null_month= b3>=(v008-1-60)-0 &b3<=(v008-1-60)-0
cohort_b_null_month= b3>=(v008-1-60)-0 & b3<=(v008-1)-0
cohort_c_null month= ifelse(b3>=(v008-1)-0 &b3<=(v008-1)-0
cohort_a_one_two_month= b3>=(v008-1-60)- & b3<=(v008-1-60)-1
cohort_b_one_two_month=b3>=(v008-1-60)-1 & b3<=(v008-1)-2 cohort_c_one_two_month= b3>=(v008-1)-2 & b3<=(v008-1)-1
# definition of deaths in cohorts(as an example age segment=0 month & 1-2 month)
cohort_a_null_month_deaths= children belong to cohort_a_null_month & b7==0 & b5==0
cohort_b_null_month_deaths= children belong to cohort_b_null_month & b7==0& b5==0
cohort_c_null_moths_deaths= children belong to cohort_c_null_month & b7==0& b5==0
cohort_a_one_two_month_deaths= children belong to cohort_a_one_two_month & b7>=1 & b7<=2& b5==0
cohort_b_one_two_month_deaths= children belong to cohort_b_one_two_month & b7>=1 & b7<=2& b5==0
cohort_c_one_two_month_deaths=children belong to cohort_b_one_two_month &b7>=1 & b7<=2& b5==0
#definition of survivors in cohorts(as an example age segment=0 month & 1-2 month)
cohort_a_null_month_survivors= children belong to cohort_a_null_month& b5==1 or children belong to cohort_a_null_month & b7>0
cohort_b_null_month_survivors= children belong to cohort_b_null_month& b5==1 or children belong to cohort_b_null_month & b7>0
cohort_c_null_month_survivors= children belong to cohort_c_null_month& b5==1 or children belong to cohort_c_null_month & b7>0
cohort_a_one_two_month survivors= children belong to cohort_a_one_two_month & b5==1 or children belong to cohort_a_one_two_month & b7>1
cohort_b_one_two_month survivors=
cohort_b_one_two_month & b5==1 or children belong to cohort_b_one_two_month & b7>1
cohort_c_one_two_month survivors= children belong to cohort_c_one_two_month & b5==1 or children belong to cohort_c_one_two_month & b7>1
numerators: as example for age segment=0
numerator for age segment 0= sums of (0.5* sums of cohort_a_null_month_deaths per individual state)+ sum of cohort_b_null_month_deaths per individual state+ sum of cohort_c_null_month_deaths per individual
denominators: as example for age segment=0
denominator for age segment 0= sums of (0.5* sums of cohort_a_null_month_survivors per individual state)+ sum of cohort_b_null_month_survivors per individual state+ sum of cohort_c_null_month_survivors per individual
Could you please tell me what I'm missing here?
