3.5.3.1.23 Poisscdf
Definition:
/math-60c1a7030e10afd7eed346bcdb5d4bab.png?v=0 "prob = poisscdf(k, lambda)")
computes the lower tail probabilities in given value /math-8ce4b16b22b58894aa86c421e8759df3.png?v=0 "k")
, associated with a Poisson distribution using the corresponding parameters in /math-c6a6eb61fd9c6c913da73b3642ca147d.png?v=0 "\lambda")
.
The lower tailed probability:
/math-8ba22f47f618250faabb93469db58852.png?v=0 "P(X\leq k)=\sum_{i=0}^kP(X=i)=\sum_{i=0}^ke^{-\lambda }\frac{\lambda ^k}{k!}")
Parameters:
- k (input,int)
- The integer which defines the required probabilities.
/math-3acdf0b0099210f9695d4958c9919492.png?v=0 "k\geq 0")
- lambda (input,double)
- The parameter of the Poisson distribution.
/math-bffd0eceec084a63a6033b29702b1284.png?v=0 "0\leq lambda\leq 1.0e6")
- prob (output,double)
- The probability.
