-----------------------------------------------
OPRC coefficients denote with increasing internet use there is a decreasing probability  of responding "COMPLETELY HAPPY" and an increasing probability of responding "NOT HAPPY AT ALL"
-----------------------------------------------
A negative AMPE denotes a decreasing probability of being "COMPLETELY HAPPY" when internet use is increasing.

A positive AMPE denotes an increasing probability of being "NOT HAPPY AT ALL" when internet use is increasing.

The results of the above analyses are robust against controlling for endogeneity of the variable NETCHAT, where a simultaneous estimation model is employed using relevant Instrumental Variables. This endogeneity approach controls for simultaneous effects of the above mentioned covariates on NETCHAT and LIFE SATISFACTION.
