Y* are a directory highlighting the merge aftereffect of X (character particular and you can technical certain) factors you to definitely influence adoption decision. Y* i s not observable. What’s, yet not, observed is if this new farmer enters into the technology (when Y* >0) or not ( whenever Y* =0). Where Y is the urban area (ha) below enhanced maize variety, X is just as laid out significantly more than, ? , ? is actually parameters to get estimated and ? was a great stochastic error term The possibilities of adoption and employ power is projected utilizing the adopting the conditional expectation form: E(Y|Y*) = Y*.F(Y*/?) + ? .f(Y*/?
