描述----------Description----------
This GUI allows users to control the density tour by simply moving and clicking their mouses. The Variable Selection checkboxes contains all the numeric variables, and at least two of them need to be checked to make the display work. All the categorical variables go to the Class Selection box. We should select the class variable by double clicking the variable names. Color isn't implemented with the density tour yet. The Tour Type radio buttons contains four different tour types. They are the Grand Tour, Little Tour, Local Tour and Guided Tour. We can only choose one type a time. For the Guided Tour, we need to choose an index from the droplist to specify which particular search type is desired. The default index would be holes. For tour type Guided(lda_pp) and Guided(pda_pp), we also need to specify class variable first, and the Guided(pda_pp) is also controlled by another parameter, lambda. Lambda ranges from 0 to 1, with default at 0.02. A value of 0 will make the tour operate like Guided(lda_pp). For high-dimensional data a value closer to 1 would be advised. The Method Type radio buttons contains three different display methods. They are histogram, density plot and ash plot. The distribution of data projected into 1d can be displayed correspondingly as a histogram, kernel density estimate and average shifted histogram. The Axes Locations column contains two choices, TRUE and FALSE. TRUE means the tour will center at the middle of x-axes, FALSE means the tour will wander to the left and right. The default value is TRUE. The Speed slider can control the speed of the 1D tour. Simply dragging the mouse along the slider, changes the speed from slow to fast. The Pause check box allow users to pause the dynamic 1D tour and have a close examination on the details. The Apply button allows users to update the 1D tour, when it doesn't automatically update. The Quit button allows users to close thie GUI window. The Help button provides information about the tour and also what this GUI can do. Tooltips will pop up when the mouse is moved over the GUI, which give hints about the functionality of the different GUI elements.
此图形用户界面允许用户通过简单的移动和点击鼠标控制密度之旅。变量选择复选框包含了所有的数字，其中至少有两个变量，需要进行检查，以使显示器工作。所有分类变量的类别选择框。我们应该选择的类变量，双击变量名。颜色不落实的密度之旅。旅游类型“单选按钮包含四个不同的旅游类型。他们是大旅游，小旅游，本地旅游及导赏。我们只能选择一种类型的时间。导赏服务，我们需要选择从下拉列表来指定特定的搜索类型所需的索引。默认的索引孔。对于旅游型制导（lda_pp）和引导（pda_pp），我们还需要先指定类变量，并引导（pda_pp），也可以控制另一个参数，λ。拉姆达范围从0到1，默认情况下为0.02。如果值为0，将在旅游经营如导游（lda_pp）。对于高维数据的值越接近1，通常会被告知。方法类型“单选按钮包含三种不同的显示方法。他们是直方图，密度图和灰图。投影到一维的数据可以显示相应的直方图，核密度估计，平均转移直方图分布。轴位置列包含两个选择，TRUE和FALSE。 TRUE巡回演唱会在x轴的中间，FALSE表示巡回演唱会游移到左侧和右侧。默认值是TRUE。速度滑块可以控制速度的1D旅游。简单的拖动鼠标沿滑块，可以改变速度由慢到快。 “暂停”复选框允许用户向暂停的动态1D旅游，在细节上有着密切的检查。应用“按钮使用户能够更新1D旅游时，它不会自动更新。退出按钮允许用户关闭世尊GUI窗口。 “帮助”按钮提供了有关旅游的信息，这个GUI可以做什么。工具提示会弹出时，鼠标移动到图形用户界面，不同的GUI元素的功能给予提示。
