WebFrom the perspective of a given distribution, the parameters are constants, and terms in a density function that contain only parameters, but not variables, are part of the normalization factor of a distribution (the multiplicative factor that ensures that the area under the density—the probability of something in the domain occurring— equals 1). Web11 de mai. de 2012 · Making a standard normal distribution in R. Using R, draw a standard normal distribution. Label the mean and 3 standard deviations above and below the (10) mean.
