0. Here are the instructions: Create 10,000 iterations (N = 10,000) of rbinom (50,1, 0.5) with n = 50 and your guess of p0 = 0.50 (hint: you will need to construct a for loop). Plot a histogram of the results of the sample. Then plot your pstar on the histogram. If pstar is not in the extreme region of the histogram, you would assume your guess
A "hit" is a 4, 5, or 6 on 1d6. Every 6 can be re-rolled to get another hit. There is a target number of hits required for success. For example, if you rolled 4 dice with a target of 2 hits, I would expect the chance of success to be around 66%. However, if you wanted to calculate the odds of getting 5 hits on 4 dice, you would need to know the

19. Binomial Distributions. One of the most important discrete distribution used in statistics is the binomial distribution . This is the distribution which counts the number of heads in n n independent coin tosses where each individual coin toss has the probability p p of being a head. The same distribution is useful when not tossing coins

First, create a new vector of x values that includes a higher density of points, to reflect the fact that the normal distribution is continuous, rather than discrete: x = seq (-5,250,length.out=2000) Now we create a data frame of normal densities with the same means and variances as the binomial densities above:
In R programming, you can use the built-in dbinom (), pbinom (), qbinom (), and rbinom () functions to work with the binomial distribution. dbinom (x, size, prob) calculates the probability mass function (PMF) of the binomial distribution at a specific value of x. size is the number of trials and prob is the probability of success on each trial.

Working with the binomial distribution in R. Although some people find it handy to know the formulas in Table 9.2, most people just want to know how to use the distributions without worrying too much about the maths. To that end, R has a function called dbinom() that calculates binomial probabilities for us. The main arguments to the function are

The standard errors calculated by stats::summary.glm use a different dispersion value for the binomial and quasibinomial families, as mentioned in stats::summary.glm: The dispersion of a GLM is not used in the fitting process, but it is needed to find standard errors. If dispersion is not supplied or NULL, the dispersion is taken as 1 for the
Suppose I have a data set consisting of values of a statistic which theoretically follows Binomial distribution with some specified parameter (say size=30, prob=0.5).
