 Usage:  mh = regxestp(x {,h {,K} {,v} })  

 

 Input:



  x                      n x (p+1), the data. In the first p columns 

                         the independent variables, in the last column 

                         the dependent variable. 

                         

  h                      scalar, p x 1 or 1 x p, bandwidth. If not 

                         given, 20% of the range of x[,1:p] is used. 

                         

  K                      string, kernel function on [-1,1] or Gaussian 

                         kernel "gau". If not given, the Quartic kernel 

                         "qua" is used. 

                         

  v                      m x p, values of the independent variable on 

                         which to compute the regression. If not given, 

                         a grid of length 100 (p=1), length 30 (p=2) 

                         and length 8 (p=3) is used in case of p<4. When 

                         p>=4 then v is set to x. 

                         

 Output:



  mh                     n x (p+1) or m x (p+1) matrix, the first p columns 

                         contain the grid or the sorted x[,1:p], the 

                         second column contains the regression estimate 

                         on the values of the first p columns.
