How can we find the correct values for the different parameters? c, C and delta?

Being surrounded by people who look like you and who are more willing to associate with you because you share their race (based on appearance) is a huge advantage that white Americans do not ever realize unless they grew up in a place surrounded by people who were not white. When I went to my mother's hometown in central Mexico, I saw so many people who looked like me, and it was so shocking and strange to experience it. My entire life, I have been surrounded by communities and schools that are over 80% White, and even then, there are very few people who are Mestizo and/or Latin American like me. People like to pretend to be colorblind and dismiss race, but racial homophily is subconscious and does exist even among young children across all races. It's a fact that people tend to associate with people who look like them, and as an only child of a Mestiza Mexican mother and White Anglo-American father, it has been very isolating. So many times in my life, I have tried to develop close bonds with white friends, but they did not work out as well as friendships I made with fellow people of color. I somehow always knew subconsciously that white people were less willing to accept me because of my race, and it is only until recently that I consciously realize it. It is subconscious for them. White Americans in most of Missouri have the privilege of never having to interact with people of a different race from them if they choose too but if I want to get ahead in life I have to interact with them even if they never fully accept me as one of them. They subconsciously don't want non-Whites in their social group no matter how hard we try to assimilate and act like them. I will not abandon my Mexican heritage and Mestizo identity to try to get White Americans to accept me because no matter what I do, they never will. I'm tired of the extreme lack of self-awareness and introspection of white Americans to put themselves in the shoes of a racial minority in an overwhelmingly white school that also happens to be mixed-race. Do they ever think for even a second about what it must be like to grow up being the only one or one of the few of your race surrounded by more privileged people of another race? It matters because people consciously and subconsciously treat you differently based on your race and appearance. It makes networking and friendships that much harder. Do they ever check their subconscious bias of racial homophily and consider trying to trach out and make friends with racial minorities?

Hello, professor. I would like to say I really appreciate your upload. I have a small question while I am listening to this: is there any different between big N and small n? I know that N is the number of nodes, but I am not sure about small n. Is n used indifferently from N? or does it have any different meaning?

Can you explain why decay centrality when delta is 0 is direct connected to all the other node and delta = 1 is indirect connected to the rest?
Thx a lot professor Matthew !! I did a very simple translation in Chinese, i hope you do not mind it. I am not professional but hope it helpful: p1 随机指数图模型的优点在于: 1. 包括更多更丰富的网络局部特征(local features)和相关性 (dependencies) - 不仅是cluster, 三元组,而是细小到clique,isolate node。 2. 方便统计估计 - 随机指数家族有良好的统计性质 p2 从历史的角度看:ergm曾被称为马尔可夫模型,p星模型。 (插播:哈哈哈哈intersting, 因为之前的模型都不够好,所以科学家搞了一堆hybrid model混血模型) 我们想要的是:link ij 形成的概率依赖于link jk 和 link lk(三元闭合)。但是这样面临了一个问题:一旦我们让边的形成相互依赖,那么以为着一切边的形成都是关联的correlated,边变成互锁的interlock,一条边影响它的邻居,它的邻居又反过来影响它(类似内生性问题??),于是我们面对的这个系统将是一个拥有大量相关性的系统。我们需要去识别整体的关联性。 p3 一个简单的例子: 1. 网络的概率 等于 网络中形成的边数量 2. 网络的概率 等于 网络中形成的三元组数量 (试想:拥有相同的边的数量,而不通过三元组数量的两个网络) p4 边的似然,取决于节点的属性,也取决于节点是否有共同的邻居。 p5 网络G的概率 依赖于 系数1*G拥有的边的数量 + 系数2*G拥有的三元组的数量 因为上述式子可能会出现负数,而概率不可能是负数,为了式子有更好的性质,所以加上exp,让图的概率可以一直是正的。 p6 在 hammer sly 1971未发表的论文中,他指出:任何的网络模型,都可以表示为指数家族with 图中的统计上的加总。 (试想,假设你有一个很复杂的具体模型,你可以写上很多很多的统计量:边,三元组,二元组,clique,点的属性,出入度分布等等等等) p7 给定网络G的概率 等于 exp(系数1*G拥有的边的数量 + 系数2*G拥有的三元组的数量) 除以(我理解下是)所有的和G有相同的节点和属性的可能的网络的 exp(系数1*G拥有的边的数量 + 系数2*G拥有的三元组的数量) 的和。(I am not pretty sure...) p8 endos-renyi gnp 为例子,最后的s1(g)是statistic , L(g), g拥有的边的数量

@socialandeconomicnetworks45865 жыл бұрын
It is a solution to a simultaneous set of equations and something that many software programs (both network software and others) can provide for moderate size networks, or approximate for larger networks. There are many eigenvectors for such a matrix, but generally a unique one (up to a rescaling) with all non-negative values for networks that we deal with in practice.
