Probability and StatisticsIn this section we present some examples to solve typical ' probability and statistics ' problems. We present the Matlab code without using any special toolbox or instruction. Everything is plain and simple... You could even code the same algorithms in other programming languages without any problem! Permutations
and Combinations This algorithm (program in Matlab) calculates the probability and frequency of given values on a standard normal distribution curve (Gauss’ bell). You have to enter the mean, the standard deviation and the value of interest...
an event occurring a given number of times. You must know the expected frequency of the event... F-distribution This algorithm calculates percentile values for given values on an F-distribution curve. You must provide the value of F, the degrees of freedom in the numerator and the degrees of freedom in the denominator... Student's t-distribution This algorithm (Matlab program) calculates right-tail values for points on a t-distribution curve. You must provide the value of t and the degrees of freedom... T-statistic - Student’s t-Test This program performs the t-statistic and degrees of freedom for Student’s distribution. The calculations can be based on any one of these three hypotheses... Chi-square distribution This program calculates the tail-end and percentile values for points on a Chi-square (X2) distribution curve. You must provide the value of X2 and the degrees of freedom. No special instruction or Matlab toolbox is used. Random Numbers and Simulations We’ll use Matlab to generate random numbers so that we can discuss its statistical capabilities and explore some simulations... Random Number Tables A random number table is a listing of random numbers where we can choose the quantity of random numbers desired, the maximum and minimum values of numbers in the table, and whether or not duplicate numbers are allowed...
