These programs determine the Probabilty Density Function (PDF) and Cumulative Probability Function (CDF) from an ASCII (text) data file:

For the three programs

  • INPUT FILE: 
      text (ASCII) data file 
      anyname.txt 
      numbers separated by (RETURN)
  • HISTOGRAM PDF OUTPUT FILE: 
      text (ASCII) data file 
      3 columns: bin center (TAB) PDF (TAB) number in bin (RETURN) 
      given the name anynameHISTPDF.txt
  • MULTISCALE PDF OUTPUT FILE: 
      text (ASCII) data file 
      2 columns: bin center (TAB) PDF (RETURN) 
      given the name anynameMULTIPDF.txt
  • RANK CDF OUTPUT FILE: 
      text (ASCII) data file 
      2 columns: value (TAB) RANKCDF (RETURN) 
      given the name anynameCDF.txt
