PredictInterval: Forecast interval accuracy

Description

PredictInterval uses Simplex to evaluate prediction accuracy as a function of forecast interval Tp.

Usage

PredictInterval(pathIn = "./", dataFile = "", dataFrame = NULL, pathOut = "./", 
  predictFile = "", lib = "", pred = "", maxTp = 10, E = 1, tau = -1, 
  columns = "", target = "", embedded = FALSE, verbose = FALSE,
  numThreads = 4, showPlot = TRUE)

Arguments

pathIn

path to dataFile.

dataFile

.csv format data file name. The first column must be a time index or time values. The first row must be column names.

dataFrame

input data.frame. The first column must be a time index or time values. The columns must be named.

pathOut

path for predictFile containing output predictions.

predictFile

output file name.

lib

string with start and stop indices of input data rows used to create the library of observations. A single contiguous range is supported.

pred

string with start and stop indices of input data rows used for predictions. A single contiguous range is supported.

maxTp

maximum value of Tp to evalulate.

E

embedding dimension.

tau

lag of time delay embedding specified as number of time column rows.

columns

string of whitespace separated column name(s) in the input data used to create the library.

target

column name in the input data used for prediction.

embedded

logical specifying if the input data are embedded.

verbose

logical to produce additional console reporting.

numThreads

number of parallel threads for computation.

showPlot

logical to plot results.

Value

A data.frame with columns Tp, rho.

Examples

# NOT RUN {
data(TentMap)
Tp.rho <- PredictInterval( dataFrame=TentMap, lib="1 100",
pred="201 500", E=2, columns="TentMap", target="TentMap", showPlot = FALSE)
# }
