 Usage:  mh = lpderxest (x, h {,q {,p {,K} {,v}}})  

 

 Input:



  x                      n x 2, the data. In the first column the 

                         independent, in the second column the 

                         dependent variable. 

                         

  h                      scalar, bandwidth. If not given, the rule of thumb 

                         bandwidth computed by lpderrot is used. 

                         

  q                      integer <=2, order of derivative. If not 

                         given, q=1 (first derivative) is used. 

                         

  p                      integer, order of polynomial. If not given, 

                         p=q+1 is used for q<2, p=q is used for q=2. 

                         

  v                      m x 1, values of the independent variable on 

                         which to compute the regression. If not given, 

                         x is used. 

                         

 Output:



  mh                     n x 2 or m x 2 matrix, the first column is the 

                         sorted first column of x or the sorted v, the 

                         second column contains the derivative estimate 

                         on the values of the first column.
