arg min ???
Hi r-help-bounces at r-project.org napsal dne 25.11.2009 16:50:49:
This is nice, but i have to define vector of possible theta, this is not
what
i want to do. I have vector of unknow parameters theta. I have som estimate of theta,
but
i want to do better estimate of them, using some criterion function. I mean it is clasical argmin f(x_1,x_2,...x_n) to fit vector (x_1,x_2...,x_n)`
I am not sure what you mean by argmin, but maybe you could look at ?optim Regards Petr

tet={tet1,tet2} .... i have they starting value
and i want to find the tet what minimalizing some function of tet ?
?which.min Perhaps: which.min( fn(tet) )
