Rbinom
Tīmeklisrbinom(30,100,.5) #小数点前的0可以省略 生成的30个随机数都在50左右徘徊。 因为每次伯努利试验（抛硬币）的成功概率是0.5，那么在理想状态下，模拟100次伯努利 … Tīmeklis2013. gada 13. jūn. · rbinom(1000, size=74, prob=0.89) I'm still a little rusty with the rbinom function. In the code above, I am generating 1000 observations of 74 trials, with the prob of success on each trial = 0.89. I want the deviates that I generate to be less than or equal to 74. How can I restrict the rbinom function to account for this?
