1. Because it defaults that the mean value of the error term is equal to zero, so after getting a group of time series data, we need to subtract the mean value of the group of data, and then use the first-order autoregression to fit.

2. The official service center of Omega Shanghai is located in room 1003, 10 / F, Hongyi International Plaza, 299 Nanjing East Road, Shanghai. Here's why the watch stops secretly:
watch stop: anyone who knows a little about the mechanical watch knows that the automatic mechanical watch completely depends on the swing of the arm to complete the winding. Therefore, once the watch is placed for a long time or the daily arm activity does not meet the requirements of the watch winding, the watch will lead to the lack of potential energy e to winding, which will cause the watch to go unstable or stop at night when it is not worn
watch knock: because the watch is exposed most of the time in the process of wearing, it is easy to knock other hard objects when walking. If you accidentally knock or fall on the watch in daily use, it may lead to the movement gear and other parts of the watch loose, dislocation and other situations, which will also lead to the mechanical watch to stop stealthily
hairspring problem: hairspring fault is also one of the reasons for the mechanical watch to stop stealthily when it is running normally. As we said earlier, some people stop their watches secretly e to insufficient activity. If the activity is too large, the winding mechanism will be broken down e to the tightening of the winding for a long time. It can also cause a lack of motivation.

4. Imperial watch official service center: [Shanghai] [Xuhui District] [Hongqiao Road] [No.3] [ganghui Henglong Plaza] [37th floor, 2 office buildings]
there are many reasons for the emperor's incorrect travel time, such as collision, movement gear dislocation, watch magnetization, etc If you have any questions that you don't understand, you can click the avatar hotline]
the emperor's rudder is out of time. You should check whether the watch is stationary for a long time. The automatic watch depends on the relative motion of the swing to wind up automatically. If it is carried in the hand and is in a relatively static state for a long time, the watch can not wind up automatically, it will lose the ability to walk and stop. The user only needs to swing the watch dozens of times or several times to wind it up (when there is a hand adjustment function), and the travel time can be restored The watch is demagnetized free of charge

5. The watch maintenance center is located in room 1003, 10 / F, Hongyi International Plaza, No. 299, Nanjing East Road, Huangpu District, Shanghai. Here is how to deal with the st in the watch:
the st in the dial of the watch is usually e to the graal infiltration of st in the process of wearing for a long time. If you only enter the fine st, you don't need to clean it without affecting the appearance and use. However, if the st with a certain length, such as hair or acrylic fiber, enters the dial of the watch, attention should be paid to it, because such st is extremely likely to cause the operation of the stop card movement

6. ‍
it is recommended that you can open the warranty sheet attached to the meter. Normally, the warranty sheet will have the service address, or you can find the address of a regular watch Service Center for inspection and maintenance, or you can find a professional after-sales service center nearby.

7. 1) Insufficient power storage: you need to check whether the power is sufficient first. If the amount of movement of the mechanical watch on the automatic chain is very small, it may also cause insufficient power storage. You can supplement the power by manually on the chain, and then observe whether the phenomenon of speed continues. 2) Insufficient power: if the quartz watch suddenly finds that it is slow, it may be caused by insufficient battery energy. You can send the watch to a special maintenance point to check the power. 3) Have been hit or hit: the watch is very tight. If it is hit or hit, it may cause internal parts to loosen and damage, and it may also cause travel time problems. 4) Need maintenance: the lack of oil in the movement or the wear and aging of internal parts may cause travel time problems, which need to be maintained and sent to the designated repair point for maintenance service.

8. The requirement of software to hardware is omni-directional. Simply increasing the frequency of one hardware does not change the performance of other hardware
if you are an overclocking professional, please ignore the following words
if you don't know much about overclocking, please read the following (just for novices, I know the space is limited)
some of the computer hardware (CPU, memory, independent graphics card, etc.) has the function of overclocking
CPUs are so precise that manufacturers can't control the frequency of each CPU
in fact, the manufacturer has done many tests by itself, marking the CPU that can work at high frequency as high frequency
however, in order to ensure its quality, these tags have a certain margin
in other words, a 2500mhz CPU is likely to work stably at 3500MHz. In order to explore these potential spare parts, overclocking can be carried out. Therefore, overclocking is not an additional function specially designed by the manufacturer
the manufacturer does not recommend users to turn on the overclocking function, because the hardware damage caused by overclocking is not within the scope of after-sales
Why do manufacturers sell hardware with overclocking function? Users or players can be divided into ordinary users and professional users from the perspective of usage
the overclocking amplitude of each hardware is a variable, not a quantity. The use of overclocking is not as simple as turning on the hardware frequency to the maximum value in the software or motherboard options
because the overclocking potential of each type of hardware is unknown, overclocking is a complex process, which needs to be mastered step by step. No overclocking expert dares to say once when contacting a certain type of hardware for the first time to know how to overclock the hardware
the frequency amplitude of each CPU is different, and the result of each overclocking is not necessarily the same. The more precise the CPU is, the more complex the control is
1. Different types, specifications, models and other hardware need to run professional software to test the overclocking value before overclocking
2 and hardware overclocking (especially CPU) also need to do the cooling measures accordingly. No cooling measures are awesome. Overclocking is equal to gambling.
3. Adjust the specific value of overclocking according to different types, specifications and models of hardware
4. Adjust the specific value of overclocking according to the requirements of software for hardware
5. Install the memory that exceeds the maximum memory frequency supported by the CPU, and the CPU will use it according to the maximum frequency it can recognize
the above factors affect the specific value of hardware overclocking (when using hardware with overclocking function, if one factor changes, the overclocking value needs to be changed accordingly. After closing the program that uses overclocking, adjust the frequency to the value before using the program in time.) People who do not have professional knowledge simply adjust the frequency to the maximum, which is equal to living beyond their means It will cause irreparable damage to people's life and health to let a person do the maximum overload exercise every minute.)
to sum up, manufacturers selling hardware with overclocking function are facing professional users with professional background. It is suggested that if non professional users want to pursue better operation effect, they can upgrade or buy a more high-end one when the RMB is sufficient For example, i5 for i7, gtx960 for gtx980, etc.)
