which variable is an independent variable? what is a normal distribution of a y variable? what is vec distribution if two random variables are independent when do you find the independent random variables a multivariate normal distribution is called a what is the function for a normally distributed sample of variable what does a normal distribution of a variable include if the sum of the independent normals is multivariate, what is the distribution of the variable y_0 which random variable is an independent variable how to find independent distribution how to find the distributions of an independent random variable if two independent variables are normally distributed what do we say about the distribution of y_0 and y_1? why is $x_0 a multivariate normal variable? what is the value of x_0 what is the distribution of the normally distributed random variables? what is independent distribution of a random variable which variables are independent or multivariate what is the distribution of independent variable which variable is not independent?
