is bootci with bootfun returning a vector possible? (at leastin newer versions of matlab)
Michalis wrote: Hi, I am trying to get confident intervals for a vector of coefficients using BCa. I found that bootci can do this work but only if the function handle returns a scalar. I use least squares to find the coefficients from the eq.: @coeff =(y) pinv(H)*y where H is a matrix and y is a vect... 18 Jun 2010 12:25
