Lecture II: Probability Density Functions and the Normal Distribution The Binomial Distribution Consider a series of N repeated, independent yes/no experiments (these are known as Bernoulli trials), each of which has a probability p of being ‘successful’. The binomial distribution gives the probability of observing exactly k successes.

probability distribution, the density function has the following properties: Since the continuous random variable is defined over a continuous range of values (called thedomain of the variable), the graph of the density function will also be continuous over that range.

What probability does the empirical CDF put on any value between x i and x i+1? Clearly, zero. This could be right, but we have centuries of experience now with probability distributions, and this tells us that usually we can expect to nd some new samples between our old ones. So we’d like to get a non-zero density between our observations.

Probability Distributions for Continuous Variables Definition Let X be a continuous r.v. Then a probability distribution or probability density function (pdf) of X is a function f (x) such that for any two numbers a and b with a ≤ b, we have The probability that X is in the interval [a, b] can be calculated by integrating the pdf of the r.v. X.

The probability distribution of X is described by a _____. The probability of any event is the area under the density curve and above the values of X that make up the event. All continuous probability models assign probability _____ to every _____ outcome.

1. We choose a probability density -- called the prior distribution – that expresses our beliefs about a parameter before we see any data. 2. We choose a probability model that reflects our beliefs about given . 3. After observing data , we update our beliefs and calculate the posterior distribution .

The probability mass function provides us with the ability to compute the probability of the load being within a range according to: We may use the probability mass function to obtain the cumulative distribution function (CDF) according to: From Fig. 8, we obtain: Plotting these values vs. the load results in the CDF of Fig. 9.

Instead we use a function, referred to as the probability density function. Probability Density Function. The function f(x) is a probability density function for the continuous random variable X, defined over the real numbers R if: f(x) > 0 for all x that are elements of R ( ( f(x)dx = 1 (b P(a < x < b) > ( f(x)dx. a

When the prior distribution P[s] is a flat, that is when there is no specific prior information about s, this is a renormalized version of the likelihood, where the renormalization ensures that it is a proper probability distribution (i.e., integrates to 1).
