非常感谢您的回答,收益颇丰。
假如这里是一个一般的分布或未知分布这个问题要怎么解决呢?
其他分布的用法与normal distribution类似,你只要知道分布的名称就行了。直接help(distribution)能够给你相关结果。
The functions for the density/mass function, cumulative distribution function, quantile function and random variate generation are named in the form dxxx, pxxx, qxxx and rxxx respectively.
For the beta distribution see dbeta.
For the binomial (including Bernoulli) distribution see dbinom.
For the Cauchy distribution see dcauchy.
For the chi-squared distribution see dchisq.
For the exponential distribution see dexp.
For the F distribution see df.
For the gamma distribution see dgamma.
For the geometric distribution see dgeom. (This is also a special case of the negative binomial.)
For the hypergeometric distribution see dhyper.
For the log-normal distribution see dlnorm.
For the multinomial distribution see dmultinom.
For the negative binomial distribution see dnbinom.
For the normal distribution see dnorm.
For the Poisson distribution see dpois.
For the Student's t distribution see dt.
For the uniform distribution see dunif.
For the Weibull distribution see dweibull.
For less common distributions of test statistics see pbirthday, dsignrank, ptukey and dwilcox (and see the ‘See Also’ section of cor.test).
未知分布?分布都未知,如何求逆累计分布?这个不知道。
