Prior probability

test is used to determine whether there is a significant difference between the expected frequencies and the observed frequencies in one or more categories. Assume n be the total number of documents in the collection, pi(w) be the conditional probability of class i for documents which contain w, Pi be the global fraction of documents containing the class i, and F(w) be the global fraction of documents which contain the word w. Then, the x2-statistic of the word between word w and class i is defined[1]

If we take a look at an example about prostate cancer, with the data collected by Hastie, Tibshirani, Friedman in The Elements of Statistical Learning [2] and view the scatterplot in figure 1.1, we can see that the dependent variable, the log of the prostate specific antigen (lpsa) has a strong positive correlation particularly with lcavol (the log cancer volume) and lcp (the log of capsular penetration) with weaker but still strong correlations with the other dependent variables, log prostate weight

Veliota Drakopoulou November 20, 2016 Final Paper This paper will give an overview of various approaches that statistics are used in everyday life when finances are concerned. The following three methods will be discussed: Sample Units, Probability, and Bayes Theorem. Hopefully, we have a broader knowledge of the three methods and understand how statistics can help in our everyday life. Let us beginning by discussing the tem statistics. “The term statistics, originated from the Latin word

The first part in the process of doing research is the question. You can 't do any research until you have an interesting and feasible question. You will base your research off this question and go through the whole process with it in mind. However, there are previous components to have ready before a question can be created for the research. These components would be: finding a topic to research, creating a theory about the topic, and collecting literature on the topic for analysis. The question

self-subsuming weight bestowal, and investigate possible counter arguments to Nozick’s proposition. The libertarian view requires a free action to be non-random, uncaused and ‘could have been done otherwise’. However, indeterminacy suggests that a prior event provides a clue of a range of probable future events. Thus the indeterministic version of event is not uncaused. To explore the possibility of indeterminacy to be compatible with free action, we have to tolerate this shortcoming. Therefore in
