Dear
how i can impose the restrictions on simultaneously the coefficients C(6), c(7) are >0 and C(1), c(2) and c(3) simultaneously lies between 0 and 1 in eviews by estimating this equation through OLS.
SE=-(c(7)/c(6)+c(7))*CEt+(c(6)/c(6)+c(7))*SEt+(1- (c(6)/c(6)+c(7)))*(c(1)*TR+c(2)*A1+c(3)*A2)

Dear i need your help.
How i can perform instrument orthogonality c-test and weak instrument test when gmm estimated through system estimation in eviews8.

thank you so much. your tip is working but know eviews produce message "near singular matrix". how i can resolve this issue?

se=(1-(c(3)/(c(3)+c(4))))*(c(10)*tr+c(20)*a1+c(30)*a2)-(c(4)/(c(3)+c(4)))*cet+(c(3)/(c(3)+c(4)))*set
what was wrong in this equation. when i try to estimate eviews produce error message"division by zero"

when we estimating system of simultaneous equations by using system estimation by gmm, in this case estimation sheet in eviews8 shows only value of jstats and not mentioning the probability of jstats. so how i can find the value of probability of jstata?
