ProbabilityIt is necessary to have a minimal knowledge of some fundamental definitions and theorems of probability and statistics to understand the principles of the different rare event probability estimation methods. The main goal of this chapter is thus to review the elementary notions on this ...

I have a survey which has categorical data, aiming to compare two groups where the general group has 56 respondents and the expert group has 6. I tried to use a Chi squared test on SPSS but more than 20% of my cells have an expected frequency of less than 5. Somehow I can’t see ...
However, sample space can also be infinite, and continuous. For continuous sample spaces, the probabilities of the single-element events may not be sufficient to characterize the probability law. A natural candidate: For a continuous model Ω = [0,1]. Define the probability on any subinterval ...
In this chapter we will cover the basic steps for getting started in R. We will discuss the pros and cons of R, how to install the software and additional packages, and some suggestions on how to set up the machine to use R efficiently. We will also see

The probability density function (PDF) is an expression used instatisticsthat defines the probability that some outcome will occur. In this function, the probability is the percentage of a dataset's distribution that falls between two criteria. PDF is commonly used byfinancial analyststo understand ...
