Is gamma distribution symmetric
The gamma distribution is the conjugate prior for the precision of the normal distribution with known mean. The matrix gamma distribution and the Wishart distribution are multivariate generalizations of the gamma distribution (samples are positive-definite matrices rather than positive real numbers).

The random variable X is distributed as X ∼ N ( 0, σ 2) In the picture below F ( a) represents the areas 1, 2 and 3. Area 4 can be calculated with the converse probability: 1 − F ( a). This area is equal to area 1.
