what is standard deviation for a lognormal distribution how to sample with a sample of lognormal distribution how to generate random distribution what is the standard deviation of a variable what is the value for emu what is the sigma of the variable if y is the sample of a standard normal distribution, the standard deviation would be: what is the standard deviation of a lognormal distribution? if a random variable x is sampled from a standard normal distribution, how many emu what is normal mean and standard deviation what does qx mean what is the sample from a standard normal distribution what if you sample from a lognormal distribution what is the standard deviation of a lognormal distribution how do you sample for a lognormal distribution what is the standard deviation in a lognormal distribution what is the standard deviation of lognormal distribution for each sample which variable is used to calculate the average deviation when we use box muller how to find the mean of x what is the standard deviation and the mean of the variable?
