TSUNFRACTION(1) TSUNFRACTION(1) NAME tsunfraction - make a cumulative sum of the fraction of change of a time series SYNOPSIS tsunfraction tsunfraction [-i value] [-t] [-v] [filename] DESCRIPTION Tsunfraction is for making a cumulative sum of the fraction of change in a time series. The value of a sample in the time series is multi- plied by the running cumulative sum of the time series, and added to the running sum of the time series. The resultant time series is printed to stdout. (This program is the inverse of the tsfraction(1) program.) Note that: tsfraction data | tsunfraction does nothing. An interesting application of this program is: tsgaussian -t 10000 | tsmath -t -m 0.01 | tsmath -t -a 0.0003 | tsunfraction which would manufacture a data file with statistics that are similar to equity market indices. The input file structure is a text file consisting of records, in tem- poral order, one record per time series sample. Blank records are ignored, and comment records are signified by a '#' character as the first non white space character in the record. Data records must con- tain at least one field, which is the data value of the sample, but may contain many fields-if the record contains many fields, then the first field is regarded as the sample's time, and the last field as the sam- ple's value at that time. OPTIONS -i value Initial value of output time series. -t Sample's time will be included in the output time series. -v Print the version and copyright banner of the program. filename Input filename. WARNINGS There is little or no provision for handling numerical exceptions.
