Hello, I work on the Stochastic Frontier Analysis (SFA) and I am looking for a function in a R package which done the multivariate interpolation.
My problem is: For all i=1, ..., n, I have values of (xi1, xi2, ..., xi7)in IR^7 and f(xi1, xi2, ..., xi7)in R and I have also values of (x'i1, x'i2, ..., x'i7) in IR^7 and I need f(x'i1, x'i2, ..., x'i7) in R by interpolation. So x is a (n,7) or a (7,n) matrix and x’ is also a matrix with the same format as x. Can someone help me? Thank you in advance.
