st: problem with marginal effect after running a logit regression

[Jeremy Franklin <jfrankli@ulb.ac.be>]

Dear all,

Here is my little trouble:

For my master degree thesis I decided to test for the role of education level in assession the importance of fighting inflation. 

Here is my final regression formula:

xi: logit mfirstchoice  mstudymid mstudyhigh mhomme mchiefwageearner mage28_37 mage38_47 mage48_57 mage58 mintpollow mintpolmid mintpolhigher mpolleft mpolright  mincomemid mincomehigh i.s003 i.s002 i.s003*i.s002, vce(cluster s003)

I hate the results but my thesis coordinator told me that the results of logit regression cannot be interpreted like coefficients of a linear regression. Therefore, he suggested me to check for the marginal effects at the median in order to see the marginal effects of one individual coming from mstudymid to mstudyhigh

I googled everything, i tried hundreds of formulas, both with mfx and margins but i still cannot find the correct one in order to interpret my results. 

Can ANYONE help me please.

ps: a robustness test included in my thesis include the following formula (this time with ologit)- 

xi: ologit minflation  mstudymid mstudyhigh mhomme mchiefwageearner mage28_37 mage38_47 mage48_57 mage58 mintpollow mintpolmid mintpolhigher mpolleft mpolright x047 i.s003 i.s002 i.s003*i.s002, vce(cluster s003)
