Hi there,
Thank you in advance for your help.
I need to do the following:
1. Take one file from excell and one from SPSS and with the data
calculate:
ESTIMATED N= SUM {1/PI(i)}; PI is the proportion
ESTIMATED T(Y)= SUM {Yi/PI(i)}; i belongs to the sample.
GINMi=[SUMi{(Yi/PI(i))*[1/PI(i)+SUMj(2/PI(j)]}]/[(2*ESTIMATED
N*ESTIMATED T)]. i belongs to M (1000,etc.) times, WHERE j=i+1
WE HAVE ONLY ONE VARIABLE Y, BUT WITH THE FIRST POSITION i AND THE
NEXT j, IN THE ASCENDING ORDER.
And last to get the errors as:
E1= [SUMi {|GINP-GINMi |}]/[M] ; i belongs M
E2= SQRT[SUMi {|GINP-GINMi |}]/[M]; i belongs TO M
Thanks,
Cesar Ortega
