Chapter 2 : Describing Distributions
... Computing Measures of the Most Likely Event We will NOT include computations for the mode because there are none. You just identify the group with the highest frequency, There are two types of equations for each measure: 1) Parametric measure. This is the real value or parameter of the population. 2 ...

... mean, values lying that far away from the mean are extremely unlikely. Even if the mean were to move right or left by 1.5σ at some point in the future (1.5 sigma shift), there is still a good safety cushion. This is why if the mean is at least 6σ away from the nearest specification limit, the proces ...

... When using samples of data, the sample mean will be the best estimate of the true population mean although there will be some uncertainty associated with this. A confidence interval quantifies this uncertainty and gives a range of values in which we are ‘confident’ the true population value will lie ...

... In this question we will use Matlab/R to explore the Poisson model with the Gamma prior considered above. (a) The Matlab (GammaPrior.m) R (GammaPrior.txt) files in the Code directory of the course web page can be used to plot the Gamma prior. Use this code to investigate different values for α and β ...
