likelihood function obtains the maximal value. The following is an example to introduce the idea and method of the maximum likelihood estimation method.
Set a bag of black and white balls. P is the probability of a white ball being randomly touched from the bag, and the value of P is to be estimated.According to the question, we make the overall Xx={1, if get white ball0, if get black ball{Then X obeys 0-1 distribution B (1,p), where P (x=1) =p, P (x=0) =1-p.For the estimation of P, we do

Installation and configuration are intuitive. I used the guide to open the Yocto project on the Intel Edison Board to install and configure the board. First we need to connect the Edison through the serial port, and configure the sshd and Wi-Fi, we can use SSH to connect to the Edison after the completion.

Reprinted from Http://www.searchsoa.com.cn/showcontent_79099.htmOver the years, node. JS has evolved into a mature development platform that has attracted many developers. There are many large, high-traffic sites that are developed using node. js, like PayPal, which developers can also use to develop some fast-moving web frameworks.In addition to Web applications, Nodejs is also used in many ways, and this article takes a count of the ten amazing projects that Nodejs has developed in other areas
In the previous article, "Wintel IoT platform-windows IoT starter Guide", we explained the setup of the Windows on device hardware preparation and software development environment, as well as a presentation of the Hello Blinky project. At the beginning of this article, we enter the project practice section.Because Windows on device is designed with Galileo as the hardware platform, its peripheral interface is also compatible with the Arduino standard.
First, the Arduino IDE downloadTo develop the Arduino 101/genuino 101, you need to install and configure the appropriate development environment first.

Widgeduino– recently unveiled on Kickstarter – is an intelligent and easy-to-configure form-based on the Microsoft Windows platform and microcontroller system communication applications based on the atmel-based Arduino board.In essence, Widgeduino communicates with the microcontroller system via a serial port protocol or TCP/IP.This includes, among other things, keyboards, LED lights, pressure gauges, knobs, sliders, thermometers, containers and butto

About the conflict between the 3D printing software Makerware and Arduion, Makerware is a software that uses the latest 3D printer Makerbot Replicator 2 for 3D model transcoding. After Makerware is started, several conveyord processes will be started. Even after Makerware is disabled, these processes still exist. Www.2cto.com these processes are constantly listening to serial USB devices, so that the printer can be detected when connected to the PC. Www.2cto.com, but the

think we have found three different numbers and killed them, the kill process is ntimes [0] And ntimes [1] minus 1. If any of them becomes 0, the corresponding candidate is cleared, here ntimes [1] minus 1 is changed to 0, so candidate [1] is to be cleared, waiting for the next value to come in.
In this way, candidate [0] and candidate [1] are the two water kings we are looking.
To expand the question, you need to find three IDs with more than 1/4 posts. You can follow my ideas.
