hello
i am a new user of R
I wonna run a double exponential function with nonlinear quantile regresion
model
the double exponential function is
Y=(
ab1978*ab1979*ab1980*ab1981*ab1982*ab1983*ab1984*ab1985*ab1986*ab1987*ab1988*ab1989*
ab1990* ab1991*ab1992*ab1993*ab1994*
6670*ab7175*ab7680*ab8185*ab8690*ab9193*abgg*abgf*abgu*abgj*abgd*abfg*abff*abfu*abfj*abfd*abug*abuf*abuj*abud*
abjg*abjf*abju*abjj*abjd*abdg*abdf*abdu*abdj*abdd*EXP(-C1*cbgg*cbgf*cbgu*cbgj*cbgd*cbfg*cbff*cbfu*cbfj*cbfd*cbug*cbuf*cbuj*cbud*cbjg*cbjf*cbju*cbjj*cbjd*
cbdg*cbdf*cbdu*cbdj*cbdd*TIMELAG)*(1-EXP(-c2*TIMELAG)) )/sqcite;
and
ab1978,ab1979,ab1980,ab1981,ab1982,ab1983,ab1984,ab1985,ab1986,ab1987,ab1988,ab1989,
ab1990, ab1991,ab1992,ab1993,ab1994,
ab6670,ab7175,ab7680,ab8185,ab8690,ab9193,abgg,abgf,abgu,abgj,abgd,abfg,abff,abfu,abfj,abfd,abug,abuf,abuj,abud,abjg,abjf,abju,abjj,abjd,abdg
,abdf,abdu,abdj,abdd,cbgg,cbgf,cbgu,cbgj,cbgd,cbfg,cbff,cbfu,cbfj,cbfd,cbug,cbuf,cbuj,cbud,cbjg,cbjf,cbju,cbjj,cbjd,
cbdg,cbdf,cbdu,cbdj,cbdd
are all dummy variable so their value might equal 0,all these variables are
vectors
and c1 and c2 are estimated parameters
can you show me how do i write this function in R
I will be grateful
Y.L Chiang
