Since it is not usual to consider a single value of a parameter, we get a posterior distribution. A posterior distribution sums up all the current knowledge about the uncertain quantities and parameters in a Bayesian analysis. It is mainly the distribution of the parameters after examining the data. However, the posterior distribution is not a good probability density function (pdf), so as to work with it as a probability function it is renormalized to obtain an integral of 1. The Bayesian inference uses the MCMC so as to draw samples from the posterior distribution which aid in getting ideas about the probability distribution function. In addition, MCMC is a methodology that provides solutions to the difficult sampling problems for the purpose of numerical integration. The basic idea behind MCMC Bayesian inference is to form or create a Markov process. This process has a stationary distribution ?(?|D) and then after forming the process run it long enough so that the resulting sample closely approximates a sample from ?(?|D). The samples obtained from this process can be used directly for parametric inferences and predictions (Chen, 2010). With independent samples, the law of large numbers ensures that the approximation obtained can be made increasingly accurate by increasing the sample size (n). The result still holds even when the samples are not independent, as long as the samples are drawn throughout the support of the ?( ?|D) in the correct proportions. Account of MCMC Bayesians Inference When using MCMC Bayesian simulation, we find out that an increase in attempts number that vary within different year performance, leads to an increase in goals, and we come up with a conclusion that scoring of this player happens with a nearly 2.3 minimum number of attempts in the corresponding continuum. The inference will be driven by a formula where we have the summation of the attempts will be posterior distributed, so by letting X be the random quantity which is discrete to denote the number of successes those are the goals. We will have a MCMC inference by developing a Markov chain with equilibrium. Every field goal scored if affected by a given number of attempt updates. Though the distribution algorithm, we generated in the creation of results we can say that there is a uniform prior leading to a sensible distribution. This posterior distribution also has a tail of infinite total probability mass of attempts but a miniscule probability on goals at each year (Lynch, 2007). The main solution behind this distribution, is to, first come up with the mean and variance from a normal distribution, when they are both known, the priors will then be written down, which will be representing some state of knowledge then come up with a posterior probability distribution for the parameters. This posterior distribution calculation on the MCMC inference simulation, will then work perfectly for the type of data given about the athlete. The goal scoring will definitely increase with an increase of the number of attempts. Model formation The Bayesian factors can be put together with prior odds so as to yield posterior probabilities of each and every hypothesis. These can be employed weighing predictions in the Bayesian model averaging (BMA). Although Bayesian Model Averaging sometimes is an effective, and efficient pragmatic tool for making predictions, the usage ...Download file to see next pagesRead More

Investment Decision Making
Firms face two main types of risk: systematic risk and unsystematic risk. Systematic risk, otherwise referred to as market risk on the one hand is the risk that a firm faces as a result of movements in the market such as movements in the value of a stock index (e.g., the FTSE100 index); fluctuations in interest rates, fluctuations in currency exchange rates, as well as changes in inflation rates.
