Human opportunity index

Hi,
I am trying to apply below mentioned HOI syntax on education data to check inequality of opportunity in education across different socio-religious categories. while running the syntax I am not getting the desired results. Also same results are showing despite changing independent variables

Am I doing something wrong.

. ssc install hoi
checking hoi consistency and verifying not already installed...
all files already exist and are up to date.

. ssc install indeplist
checking indeplist consistency and verifying not already installed...
all files already exist and are up to date.

. hoi elementary_crnt_atdns ( urban male )
