译者:生物统计家园网 机器人LoveR
描述----------Description----------
Method for multiple forecasting from a variety of univariate GARCH and ARFIMA models.
多从各种单变量GARCH和ARFIMA模型预测方法。
用法----------Usage----------
multiforecast(multifitORspec, data = NULL, n.ahead = 1, n.roll = 0,
out.sample = 0,
external.forecasts = list(mregfor = NULL, vregfor = NULL), parallel = FALSE,
parallel.control = list(pkg = c("multicore", "snowfall"), cores = 2), ...)
参数----------Arguments----------
参数:multifitORspec
Either a univariate GARCH or ARFIMA multiple fit object uGARCHmultifit and ARFIMAmultifit, or alternatively a univariate GARCH or ARFIMA multiple specification object of class uGARCHmultispec and ARFIMAmultispec with valid parameters supplied via the setfixed<- function in the individual specifications.
单变量GARCH或ARFIMA多个合适的对象uGARCHmultifit和ARFIMAmultifit,或者一个单变量GARCH或ARFIMA多个规格类的对象uGARCHmultispec和ARFIMAmultispec提供有效的参数通过setfixed<-功能在个别规格。
参数:data
Required if a multiple specification rather than a multiple fit object is supplied. A multivariate data object. Can be a matrix or data.frame object, no other class supported at present.
时需要的倍数的规范,而不是一个多个适合对象供给。一个多元数据对象。可以是一个矩阵或数据框对象,目前支持的任何其他类别。
参数:n.ahead
The forecast horizon.
预测水平。
参数:n.roll
The no. of rolling forecasts to create beyond the first one.
没有。滚动预测,以创造超越第一个。
参数:out.sample
Optional. If a specification object is supplied, indicates how many data points to keep for out of sample testing. If this is not a vector equal to the column dimension of the data, then it will be replicated to that dimension, else it must be of same length as the data column dimension.
可选。如果提供一个规范的对象,表示保留多少个数据点出样品测试。如果这是不相等的矢量列维度的数据,那么它会被复制到该维度,否则它必须是相同的长度的数据列维度。
参数:external.forecasts
A list with forecasts for the external regressors in the mean and/or variance equations if specified.
如果指定的平均值和/或方差方程外部回归预测的列表。
参数:parallel
Whether to make use of parallel processing on multicore systems.
是否利用多核系统上的并行处理。
参数:parallel.control
The parallel control options including the type of package for performing the parallel calculations ("multicore" for non-windows O/S and "snowfall" for all O/S), and the number of cores to make use of.
并行控制选项,包括包的类型进行并行计算(多核非Windows O / S和“降雪”,所有的O / S),核心数量的利用。
参数:...
.
。
值----------Value----------
A uGARCHmultiforecast or ARFIMAmultiforecast object containing details of the multiple GARCH or ARFIMA forecasts. See the class for details.
AuGARCHmultiforecast或ARFIMAmultiforecast物件,其中包含的细节多元GARCH或ARFIMA预测。有关详细信息,请参阅类。
