 Usage:  erg = wavetest(x,y,p{,dis{,data{,adjust}}}})  
 
 Input:

  x                      n x d matrix , the observed explanatory variable where 
                         all dummy inputs (0-1 variables) are expected to be in 
                         the last ('dis') columns. 
                         
  y                      n x 1 matrix , the observed response variable 
                         
  p                      scalar , the polynomial degree of the Hypothesis, 
                         see Description. 
                         
  dis                    scalar , the number of dummy variables in x. 
                         Have to be the last columns in x. Default is dis=0. 
                         
  data                   optional string, if output file for the wavelet 
                         coefficient estimates is wished, this string will be 
                         the name of that output file. 
                         
  adjust                 optional 2 x 1 vector, multiplicators for the critical 
                         values. E.g. adjust=(0.5, 1) give about 5% first kind 
                         error, adj=(1, 2.5) give about 1%. Default is (1, 1). 
                         For details see Haerdle, Sperlich, Spokoiny (1997). 
                         
                         
 Output:

  erg                    object of string, the table of results 
                         
  data                   data file , containing the wavelet estimates
