Web26 de jan. de 2024 · The area under the curve of the Normal density is 1 by definition. You have a mismatch in scales. You need either to convert your histogram to represent proportions, or scale your density to reflect the number of observations. [The clue is in the values on the y-axis. The value of N (0, 1) at 0 (the mode) is only 0.4 or thereabouts. The normal distribution is the only distribution whose cumulants beyond the first two (i.e., other than the mean and variance) are zero. It is also the continuous distribution with the maximum entropy for a specified mean and variance. Geary has shown, assuming that the mean and variance are finite, that the normal distribution is the only distribution where the mean and variance calculated from a set of independent draws are independent of each other. david hafernik je gay https://wdcbeer.com
