BINOM.DIST in Excel

BINOM.DIST in Excel Calculations with the binomial distribution formula can quite tedious and difficult. The reason for this is due to the number and types of terms in the formula.  As with many calculations in probability, Excel can be utilized to expedite the process. Background on the Binomial Distribution The binomial distribution is a discrete probability distribution. In order to use this distribution, we need to make sure that the following conditions are met: There are a total of n independent trials.  Each of these trials can be classified as a success or failure.The probability of success is a constant p. The probability that exactly k of our n trials are successes is given by the formula: C( n, k) pk (1 - p)n – k. In the above formula, the expression C( n, k) denotes the binomial coefficient. This is the number of ways to form a combination of k elements from a total of n. This coefficient involves the use of the factorial, and so C(n, k) n!/[k!(n – k)! ]. COMBIN Function The first function in Excel related to the binomial distribution is COMBIN. This function calculates the binomial coefficient C( n, k), also known as the number of combinations of k elements from a set of n. The two arguments for the function are the number n of trials and k the number of successes. Excel defines the function in terms of the following: COMBIN(number, number chosen) Thus if there are 10 trials and 3 successes, there are a total of C(10, 3) 10!/(7!3!) 120 ways for this to occur. Entering COMBIN(10,3) into a cell in a spreadsheet will return the value 120. BINOM.DIST Function The other function that is important to know about in Excel is BINOM.DIST. There are a total of four arguments for this function in the following order: Number_s is the number of successes. This is what we have been describing as k.Trials are the total number of trials or n.Probability_s is the probability of a success, which we have been denoting as p.Cumulative uses an input either of true or false to calculate a cumulative distribution. If this argument is false or 0, then the function returns the probability that we have exactly k successes. If the argument is true or 1, then the function returns the probability that we have k successes or less. For example, the probability that exactly three coins out of 10 coin flips are heads is given by BINOM.DIST(3, 10, .5, 0). The value returned here is 0.11788. The probability that from flipping 10 coins at most three are heads is given by BINOM.DIST(3, 10, .5, 1). Entering this into a cell will return the value 0.171875. This is where we can see the ease of using the BINOM.DIST function. If we did not use software, we would add together the probabilities that we have no heads, exactly one head, exactly two heads or exactly three heads. This would mean that we would need to calculate four different binomial probabilities and add these together. BINOMDIST Older versions of Excel use a slightly different function for calculations with the binomial distribution. Excel 2007 and earlier use the BINOMDIST function. Newer versions of Excel are backward compatible with this function and so BINOMDIST is an alternate way to calculate with these older versions.

The central concepts of finance - Essay Example In this case therefore, as argued by Bodie, et al, (2011), if the market is not able to predict its fluctuations, but does asses them as being likely or less likely, then the likelihood can be accessed through mathematical process using the relevant information in the market. Thus, factors such as price reflect all the relevant information that is available in terms of the total value of an asset. With the introduction and analysis of the financial efficiency, this paper provides a comprehensive analysis of the market efficiency types and the approaches to test this efficiency. After the emergence of stock market, there was a widespread concern and controversy that made most of the investors to be keen when participating in the market. The situation was caused by the fact that their approach of making their profits seemed inappropriate. Considering that the stock market is an important component of the capital market, many economists in the world developed serious concerns and intere sts in exploring the trend of stock price. In this case, even though the intentions were different, there has been a central focus on the trend of the capital market in the global financial market. As the efficient market hypothesis became known to many, it became also an important part of the school of rational expectations theory, and one of the theoretical foundations of modern economic principles. As argued by the America financial economist, Fama (1965), if the market price fully reflect the all of available information.
