Source code of blockchain mall

1. You can go to cloudleopard technology, and the team is more experienced.

2. There are too many factors that affect the price. For example, different companies may set different prices, and the complexity of software functions may also affect the price. Then there are development cycles, extended functions and so on. I don't think you will get a satisfactory answer if you don't have in-depth communication with blockchain app development companies.

3. Shopping mall shopping mall shopping mall is still in the development stage, and now it is still young. Block chain mall also needs great technical strength and accumulation. Now the frontier is to develop more than a year's online shopping mall, which is also available soon after the official account.

5. Regulatory variables can be qualitative or quantitative. In the analysis of regulatory effect, the independent variable and regulatory variable should be transformed centrally. Brief model: y = ax + BM + CXM + E. The relationship between Y and X is characterized by regression coefficient a + cm, which is a linear function of M, and C measures the size of the moderating effect. If C is significant, it means that the regulatory effect of M is significant. 2. Analysis method of regulatory effect analysis method of significant variable: divided into four cases. When the independent variable is a category variable and the moderating variable is also a category variable, the analysis of variance of two factor interaction effect is used, and the interaction effect is the moderating effect; When the regulatory variable is a continuous variable, the independent variable uses the pseudo variable, centralizes the independent variable and the regulatory variable, and does the hierarchical regression analysis of y = ax + BM + CXM + e: 1. Do the regression of y to X and m, and get the determination coefficient R1 2. 2. The regression of y to x, m and XM yielded R2 2. If R2 2 was significantly higher than R1 2, the regulatory effect was significant. Or, XM regression coefficient test, if significant, the regulatory effect is significant; When the independent variable is a continuous variable, the regulating variable is a category variable, grouping regression: grouping according to the value of M, doing y to x regression. If the difference of regression coefficient is significant, the regulation effect is significant. When the regulation variable is a continuous variable, the hierarchical regression analysis of y = ax + BM + CXM + e is done as above. There are two ways to analyze the moderating effect of latent variables: one is that the moderating variable is the category variable and the independent variable is the latent variable; The second is that both regulatory variables and independent variables are latent variables. When the moderator is a class variable, group structural equation analysis is performed. The method is to limit the regression coefficients of the two groups of structural equations to be equal, and get one χ 2 and the corresponding degrees of freedom. Then remove this restriction, re estimate the model, and get another one χ 2 and the corresponding degrees of freedom. ahead χ 2 minus the following χ 2 get a new one χ 2, the degree of freedom is the difference between the two models. If χ If the test result is statistically significant, the moderating effect is significant; When regulatory variables and independent variables are latent variables, there are many different analysis methods. The most convenient one is the unconstrained model proposed by marsh, Wen and Hau. 3. The definition of intermediary variable is the influence of independent variable x on dependent variable y. if x influences y by influencing variable m, then M is called intermediary variable. Y=cX+e1, M=aX+ e2 , Y= c′X+bM+e3 Where C is the total effect of X on y, AB is the mediating effect through M, and C 'is the direct effect. When there is only one mediating variable, there is C = C ′ + AB between the effects, and the mediating effect is measured by C-C ′ = ab. 4. Mediating effect analysis method mediating effect is indirect effect, regardless of whether the variables involve latent variables, structural equation model can be used to analyze mediating effect. The first step is to test system C. if C is not significant and the correlation between Y and X is not significant, stop the mediating effect analysis, and if it is significant, proceed to the second step; The second step is to test a and B once. If they are all significant, then test C ′, C ′, and the mediating effect is significant. If C ′ is not significant, then the complete mediating effect is significant; If at least one of a and B is not significant, do Sobel test, significant mediating effect is significant, not significant mediating effect is not significant. The statistic of Sobel test is Z = ^ A ^ B / SAB, in which ^ A and ^ B are estimates of a and B respectively, SAB = ^ a2sb2 + b2sa2, SA and Sb are standard errors of ^ A and ^ B respectively. 5. Comparison between moderator and mediator moderator m moderator m research purpose when does x affect y or when does x have a greater impact? How does x affect the moderating effect, interaction effect, mediating effect of y-related concepts When the influence of X on y is considered, the influence of strong x on y is strong and stable. The typical model is y = am + BM + CXM + e, M = ax + E2, y = C ′ x + BM + E3. The position of m in the model is x, M is in front of Y, M can be in front of X, the function of m after X and before y affects the direction (positive or negative) and strength of the relationship between Y and X. x influences the relationship between Y, m and X, X and X through it The correlation between M and X, y can be significant or not (the latter is ideal) the correlation between M and X, y is significant effect regression coefficient C regression coefficient proct AB effect estimate ^ C ^ A ^ B effect test whether C is equal to zero, AB is equal to zero test strategy do hierarchical regression analysis, test the significance of partial regression coefficient C (t test); 6. SPSS operation method of mediating effect and moderating effect. First, descriptive statistics, including M SD and internal consistency reliability (a) are used. Second, all variables are correlated, including statistical variables and hypothetical x, y, y, Third, regression analysis To choose linear regression in regression, we should first centralize the independent variable and m, that is, subtract their respective mean. 1. Now, we input m (regulatory variable or intermediary variable), y dependent variable, and demographic variable related to any of the independent variable, dependent variable, and M regulatory variable into independent. 2. Then press next to input x independent variable (intermediary variable so far). 3 In order to do the adjustment variable analysis, it is necessary to input the opportunity of X and m in the next for further regression. The test mainly depends on whether f is significant

7. Jiao Yi Mao, a place to save money for you

8. First of all, mining. If you want to rush up, it is necessary to add 5 to mining, which can save you a lot of time. First of all, it's necessary to explain. I don't think it's necessary to take a mining map to find it. A map is not big enough. You can find out where to brush it if you visit it twice. If you blindly pursue mining by mining map, you may be misled. There is also the practice of mining to take less time to practice, such as 2 o'clock in the evening, ha ha

before 75, you can go outside the main city to mine copper and smelt copper. After 75, you can go to the map above the barren land. Copper mining and tin mining have smelted bronze until 125 (if FM + 5 to 120 is OK, the rest is the same, you can leave 5 o'clock in advance). This stage is a difficult one, Don't speculate. It's futile to look for a fixed place to brush silver

125. The recommended location is arahi highland. Turn around the surrounding mountains. If you have a hole, you can enter it. If no one grabs it with you, it won't take long to reach 175

175 recommended places for collecting Mitsui are wasteland or cintland, both of which are Mitsui's paradise. If someone grabs it from you, change it to another map. It's also around the mountains. It's important to note that there is a cliff on the far right side of singland. Don't fall down. If you don't fall down and you're not dead, I suggest you drown in the water and resurrect directly. In these two places, 250 is the best

250 the recommended location for silver mining is burning plain or Fairwood. There are several ore brushing points in fat man cave, but it's not easy to find out which cave it is in. Therefore, if you are not familiar with the situation in the cave, it's recommended not to mine it. Just go around the mountain. These two places don't need to stay for long. Just go to 275<

275 the wormhole of hilisus, the recommended place for collecting silver from fuser, is absolutely a paradise. As long as you choose the right time, it will soon be 300. The key is to be familiar with the wormhole map. Or you can choose to go to Dongquan Valley, where there are many rich mines, but the map is too big to run

300 magic iron ore Hellfire Peninsula, turn around Hellfire, if you have big birds, of course it will be quite fast. Again, don't believe in the distribution map of mineral deposits. Your memory is better than anything else. It's only 330 here

Daofeng mountain, 330 Jingjin mine, is really a paradise for miners. You can graate here
