Running statistics
Description
This module computes running statistical values over a selected number of timesteps. Depending on the chosen operator the minimum, maximum, range, sum, average, variance or standard deviation of a selected number of consecutive timesteps read from infile is written to outfile. The time of outfile is determined by the time in the middle of all contributing timesteps of infile. This can be change with the CDO option –timestat_date <first|middle|last>.
Usage
cdo_runavg(ifile, nts = NULL, ofile = NULL)
cdo_runmax(ifile, nts = NULL, ofile = NULL)
cdo_runmean(ifile, nts = NULL, ofile = NULL)
cdo_runmin(ifile, nts = NULL, ofile = NULL)
cdo_runrange(ifile, nts = NULL, ofile = NULL)
cdo_runstd(ifile, nts = NULL, ofile = NULL)
cdo_runstd1(ifile, nts = NULL, ofile = NULL)
cdo_runsum(ifile, nts = NULL, ofile = NULL)
cdo_runvar(ifile, nts = NULL, ofile = NULL)
cdo_runvar1(ifile, nts = NULL, ofile = NULL)
Arguments
ifile |
String with the path to the input file. |
nts |
INTEGER - Number of timesteps |
ofile |
String with the path to the output file. |
Details
runmin Running minimum
o(t+(nts-1)/2,x) = min\{i(t,x), i(t+1,x), ..., i(t+nts-1,x)\}
runmax Running maximum
o(t+(nts-1)/2,x) = max\{i(t,x), i(t+1,x), ..., i(t+nts-1,x)\}
runrange Running range
o(t+(nts-1)/2,x) = range\{i(t,x), i(t+1,x), ..., i(t+nts-1,x)\}
runsum Running sum
o(t+(nts-1)/2,x) = sum\{i(t,x), i(t+1,x), ..., i(t+nts-1,x)\}
runmean Running mean
o(t+(nts-1)/2,x) = mean\{i(t,x), i(t+1,x), ..., i(t+nts-1,x)\}
runavg Running average
o(t+(nts-1)/2,x) = avg\{i(t,x), i(t+1,x), ..., i(t+nts-1,x)\}
runstd Running standard deviation
Normalize by n.
o(t+(nts-1)/2,x) = std\{i(t,x), i(t+1,x), ..., i(t+nts-1,x)\}
runstd1 Running standard deviation (n-1)
Normalize by (n-1).
o(t+(nts-1)/2,x) = std1\{i(t,x), i(t+1,x), ..., i(t+nts-1,x)\}
runvar Running variance
Normalize by n.
o(t+(nts-1)/2,x) = var\{i(t,x), i(t+1,x), ..., i(t+nts-1,x)\}
runvar1 Running variance (n-1)
Normalize by (n-1).
o(t+(nts-1)/2,x) = var1\{i(t,x), i(t+1,x), ..., i(t+nts-1,x)\}
Value
Operators that output one or more files return a character vector to the output files.
Operators that output an indefinite number of files return a string with the basename of the files.
Operatos that don't return filenames return a character vector with the string output.
