描述----------Description----------
Calculates plotting information for a wavelet density estimate from high level scaling function coefficients.
计算标图信息,从高层次的尺度函数系数的小波密度估计。
用法----------Usage----------
denplot(wr, coef, nT=20, lims, n=50)
参数----------Arguments----------
参数:wr
Scaling function coefficients, usually at some high level and usually smoothed (thresholded).
缩放功能系数,通常是在一些高层次的,通常平滑处理(阈值)。
参数:coef
The output from denproj for this analysis, i.e. the object containing the empirical scaling function coefficients. This is required because of the information it contains about the wavelet filter used, the resolution of the projection, and the bounds on the translation index of the scaling function coefficients.
此分析的输出denproj,即对象,其中包含的经验尺度函数系数。这是必要的,因为它包含的信息所使用的小波滤波器,分辨率的投影,翻译界的尺度函数系数指标。
参数:lims
Vector containing the minimum and maximum x values required on the plot.
Vector,其中包含所需要的最小和最大x值的图。
参数:nT
The number of iterations to be performed in the Daubechies-Lagarias algorithm, which is used to evaluate the scaling functions of the specified wavelet basis at the plotting points.
中要进行的Daubechies的Lagarias算法,该算法被用于评估在绘图点的缩放功能的指定的小波基的迭代的数量。
参数:n
The number of points at which the density estimate is to be evaluated.
的点的数量,在该密度估计要被评估。
Details
详细信息----------Details----------
The density estimate is evaluated at n points between the values in lims. This function can be used to plot the empirical scaling function density estimate by entering wr=coef$coef, but since the empirical coefficients are usually found at some very high resolution, such a plot will be very noisy and not very informative. This function will be of much more use as and when thresholding function are included in this density estimation package.
密度估计在n点之间的值lims评价。此功能可用于绘制进入wr=coef$coef,但由于经验系数通常是在一些非常高的分辨率,这样的图会很嘈杂,而不是非常丰富的经验缩放功能密度估计。此功能将是更作为阈值函数时,在这个密度估计包。
值----------Value----------
