We know that for a U [a, b] distribution, the mean µ is given by the following equation: For U [0, θ] distribution, a = 0 & b = θ, we get: Thus, if we estimate µ, we can estimate θ. To estimate µ, we use a very popular estimator called the sample mean estimator. The sample mean is the sum of the random sample value ... histeroskopi
