Binomial: The Binomial Distribution

SpletThe binomial distribution with size = n and prob = p has density. p (x) = Choose (n,x) p^x (1-p)^ (n-x) for x = 0, ..., n . If an element of x is not integer, the result of dbinom is zero, with a warning. The quantile is defined as the smallest value x such that F (x) >= p, where F is the distribution function. Splet26. jul. 2024 · pnorm函数还能使用lower.tail参数，如果lower.tail设置为FALSE，那么pnorm()函数返回的积分就是从q到正无穷区间的PDF下的曲线面积，因此我们就知道了，pnorm(q)与1-pnorm(q,lower.tail=FALSE)的结果是一样的，如下所示： bobby yarbroughSplet02. maj 2024 · If you wanted to calculate the probability of a woman having a hair length larger or equal to 30 centimers, you can set the lower.tail argument to FALSE.

SpletHowever, the documentation for R states that for the pbinom () function lower.tail logical; if TRUE (default), probabilities are P [X≤x], otherwise, P [X>x]. Therefore, if we specify lower.tail=FALSE we will not be including the first value since we are then looking at a "greater than" situation. SpletDescription Density, distribution function, quantile function and random generation for the binomial distribution with parameters sizeand prob. This is conventionally interpreted as the number of successesin sizetrials. Usage dbinom(x, size, prob, log = FALSE) pbinom(q, size, prob, lower.tail = TRUE, log.p = FALSE)

SpletThe pbinom function normally assumes that you want the lower tail of the distribution, that is the probability of getting less than or equal to a specified value. The specification "lower.tail=FALSE" tells R to compute the upper tail of the distribution, that is the probability of getting a value greater than the argument.
