描述----------Description----------
This function is merely a call to the GetRSSWST function.
此功能仅仅是GetRSSWST函数的调用。
用法----------Usage----------
wvcvlrss(threshold, ndata, levels, type, filter.number, family, norm,
verbose, InverseType)
参数----------Arguments----------
参数:threshold
the value of the threshold that you wish to compute the error of the estimate at
您要计算误差的估计值的阈值
参数:ndata
the noisy data. This is a vector containing the signal plus noise. The length of this vector should be a power of two.
噪声数据。这是一个向量,包含的信号加噪声。此向量的长度应该是二的幂的。
参数:levels
the levels over which you wish the threshold value to be computed (the threshold that is used in computing the estimate and error in the estimate). See the explanation for this argument in the threshold.wst function.
水平超过你所希望的阈值(临界值,用于计算的估计和错误的估计)计算。这种说法的解释threshold.wst功能。
参数:type
whether to use hard or soft thresholding. See the explanation for this argument in the threshold.wst function.
是否要使用硬质或软质的阈值。这种说法的解释threshold.wst功能。
参数:filter.number
This selects the smoothness of wavelet that you want to use in the decomposition. By default this is 10, the Daubechies least-asymmetric orthonormal compactly supported wavelet with 10 vanishing moments.
选择要使用的分解小波的平滑度。默认情况下,这是10,至少不对称的Daubechies正交的紧支撑小波与10个消失矩。
参数:family
specifies the family of wavelets that you want to use. The options are "DaubExPhase" and "DaubLeAsymm".
指定要使用的小波家庭。的选项“DaubExPhase”和“DaubLeAsymm”。
参数:norm
which measure of distance to judge the dissimilarity between the estimates. The functions l2norm and linfnorm are suitable examples.
测量的距离来判断估计数之间的差异性。的功能l2norm和linfnorm是合适的例子。
参数:verbose
If TRUE then informative messages are printed during the progression of the function, otherwise they are not.
如果TRUE的信息性消息时打印的功能的进展,否则他们是不会。
参数:InverseType
The possible options are "average" or "minent". The former uses basis averaging to form estimates of the unknown function. The "minent" function selects a basis using the Coifman and Wickerhauser, 1992 algorithm to select a basis to invert.
可能的选项是“平均”或“minent的”。前者使用基础上平均形成的未知函数的估计。 “minent”功能选择使用Coifman和Wickerhauser的,1992年算法选择的基础反转的基础。
Details
详细信息----------Details----------
This function is merely a call to the GetRSSWST function with a few arguments interchanged. In particular, the first two arguments are interchanged. This is to make life easier for use with the nlminb function which expects the first argument of the function it is trying to optimise to be the variable that the function is optimised over.
此功能仅仅是几个论点互换GetRSSWST函数的调用。尤其是前两个参数是互换的。这是为了使生活更轻松的使用nlminb预计它试图优化的功能进行了优化的变量的函数的第一个参数的函数。
值----------Value----------
A real number which is estimate of the error between estimate and truth at the given threshold.
一种实数,它是在给定的阈值之间的误差估计和真理的估计。
