The Outliertest () function can obtain the maximum normalized residual value bonferroni the adjusted p-value:> Library (CAR)> Outliertest (FIT)Rstudent unadjusted p-value Bonferonni pNevada 3.542929 0.00095088 0.047544You can see that Nevada is determined to be a outliers (p=0.048). Note that the function simply determines if

# sample Datad The figure 1a does isn't draw any lines, while the figure of 1b works well.The key concept is a "group" in AES.The rule is simple: Geom_line () tries to connect data points this belong to same group. Different levels of factor variable belong to different group. So, by specifying GROUP=G in AES, the lines appear in Figure 1b.Figure 1c would help to understand more.In Figure 1c, all data points belong to Group=1, hence all data points is connected.REF:http://www.m

the future to control the situation, so I think: Enterprise Certificate will not , as for distribute application way will not exit the historical stage, It depends on how many users will be able to cross this threshold under the operation of such a platform. However, helper class application The road is destined to be more and more narrow, the more difficult to go. NBSP;NBSP; Reprint Please specify: Zero Status? Small Z Observation: Whethe

// 1. Key-value observation// 2. It provides a mechanism. When the attribute of the specified object is modified, the object will receive a notification.// 3. Only objects that comply with the KVC (key-valuedcoding) mechanism can use KVO.// 4. Implementation Process// ① Register and specify the observer// ② Implement the callback Method// ③ Remove observation - ( void )viewDidLoad { [ super viewDidLoad ];

CocoaListening, observing, andNotificationThe five methods are described in this article. This article introduces the observer mode in Objective C, which is also called the broadcaster/listener, publish/register, orNotification) And the value of each method. This article will include: 1. Manual broadcasters and listeners Broadcaster and listeners) 2. Key-Value observation Key Value Observing) 3. Notification center) 4. Context notification) 5. Delegat

Top: dynamically observe process changes. ps indicates the process status at a certain time point, while top indicates dynamically observe the running status of the process in real time. We can divide the result of the top command into three parts, which is roughly like the following. The first part is the overall statistics of the system. The first line is the task queue... Top: dynamically observe process changes Ps is the state of the process at a certain time point, while top is the dynami

;public applicant (String name) {this.name = name;} @Overridepublic void Update (Subject Subject) {Headhunter H = (headhunter) subject;out.println (name + "received notification:" + H.getjobnam E ());}}The function of this applet is that once Headhunter's Setjobname () method is called (that is, there is a new job), Headhunter immediately notifies it that the applicant tells them to have a job. The program test code such as the following:public static void Main (string[] args) {headhunter hh = n

Just a summary of self-experience, there are many places to learn to practiceI use the equipment is 150/750 cow anti, equatorial instrument electric with tripodLet's talk about the use of the sky I know.A pair of polar axesTake out the lower body of the sky looking, do not install heavy hammer, this is very lightPlaced to the point of observation, to the polar axis. Polar mirror, drift, I've never used it.My approach is simple and practical, and does

Sar is a very useful system observation command in linux. It can observe disk io, cpu, block device, memory, swap, and other information to help us review the operating system status. The following lists some common system status display commands.Sar-B: disk IO transmission statisticsFive values are displayed by default: Tps: the total number of io requests sent to physical devices per second. The value is equal to rtps + wtpsrtps: Total number of rea

Polarized (bias): measure the background noise before CCD is enabled (0 s. Dark stream (dark): The Hot electrons produced by CCD itself. The number is very small, generally 1 ~ 2/s, which can be ignored. The exposure time is the same as the actual observation time. Flat field: first, a uniform color light is used to illuminate the CCD to obtain the ratio of electrons produced by each part of the CCD. Then, the actual data measured in the future is d

the current Internet development changes it. Although the flow cannot be used to measure the success or failure of the transformation, but according to my thoughts and views, also did not calculate the success of the transformation. In the last six months, I also write a blog, found to do a blog site is really very difficult, to the article Shawshank Redemption Classic lines excerpt and sentiment appreciation to analyze, you can see the effect of the article is very low, if it is LU Songsong bl

Example: About Sogou (Sogou) search engine site ranking observation Proof often use Sogou high-speed browser friends know that Sogou has a Sogou rank calculation rule. 　　 Sogou Rank Web Rating rules This is Sogou measure the importance of the index, remember should be in a long time Google did not update Google Page rank, Sogou Web rating range from 0 to 100, change to 0 to 10. This score is divided into 10 levels as Google's PR score.

The recent adjustment of Baidu everyone knows, I wrote yesterday, "Baidu algorithm adjustment test results and solutions", today, the observation of yesterday to make a summary, the morning observation is not bad, Harbin website design and the production of Harbin website to restore the first Baidu, see the kind of adjustment to see small effects, but also found a problem, This time Baidu may be the test of

I come to the world with ignorance, to live in ignorance, to leave the world with ignorance, to be well aware of my ignorance and to be more humble. the life of a person must be accompanied by ignorance, to learn, but can not be filled with the knowledge fragments for sports capital;knowledge is endless and limitless, and only by mastering the methods and ways of doing things can we deal with the environment of illusion;the limit of technology is known as the "obvious hidden" field, so the limit

The two cameras photograph the same target from two points at a certain distance. The overlapping images are called stereo images. A necessary condition for a stereo image pair is that the image overlapping degree is greater than 53%. Two remote sensing images will be arranged side by side. If the left eye looks at the image on the left and the right eye looks at the image on the right, it will produce the stereoscopic visual effect of the target object, which is called stereoscopic

The rotation matrix can be constructed by observing vectors, which can be two or three points in 3D space. If an object at Point P1 faces point P2, the observed vector is the P2-P1, for example: First, the forward axis vector is simply calculated using the normalized observation vector. Secondly, the Left axis is calculated by specifying the difference between the vector in the upward direction and the forward axis. The upward vector is used to deter

is (, 1 ), after the translated model matrix is changed to (1, 2, 1), and the person is in the four or five degrees of observation in front of the source oblique, So multiply by the view matrix to transform to the human's horizon coordinate system, after the point is changed, the point is taken as the origin point by the human eye, and the coordinate system with the observation direction as the Z negative
