STATS_RAND_GEN_BETA(3) 1 STATS_RAND_GEN_BETA(3)stats_rand_gen_beta - Generates beta random deviateSYNOPSIS
float stats_rand_gen_beta (float $a, float $b)
DESCRIPTION
Returns a random deviate from the beta distribution with parameters A and B. The density of the beta is x^(a-1) * (1-x)^(b-1) / B(a,b) for
0 < x <. Method R. C. H. Cheng.

Property Documentation
- alpha [read], [write], [nonatomic], [assign]
The value of alpha. Default is 0.0 The default value 0.0 is not recommended and is preserved for backwards compatibility. With alpha 0, it
performs a local mean subtraction. The MPSCNNLocalContrastNormalizationNode used with the MPSNNGraph uses 1.0 as a default.
- beta [read], [write], [nonatomic], [assign]
The value of beta. Default is 0.5
- delta [read], [write], [nonatomic], [assign]
The value of delta. Default is 1/1024
- (NSUInteger) kernelHeight [read], [nonatomic], [assign]
- (NSUInteger) kernelWidth [read], [nonatomic], [assign]
- p0 [read], [write], [nonatomic], [assign]
The value of p0. Default is 1.0
- pm [read], [write], [nonatomic], [assign]
The value of pm. Default is 0.0
- ps [read], [write], [nonatomic], [assign]
The value of ps. Default is 1.0
