Cdf Of Standard Normal Distribution. The CDF of the standard normal distribution is denoted by the Phi function. VarXσ 2 mean XNμσ2 CDF. Thus the cumulative distribution function is. This can be used to compute thecumulative distribution functionvaluesfor the standard normal distribution.
The distribution has a mean of 0 zero and a standard deviation of one. This can be used to compute thecumulative distribution functionvaluesfor the standard normal distribution. The cdf of normal distribution does not have a closed form. TagEquation 25 CDFPhiXPX leq xint_-inftyx frac1sqrt2piexpfrac-x22 cdotp dx. The CDF of the standard normal distribution is denoted by the Phi function. Cdf of standard normal distribution is denoted by.
The cumulative distribution function cdf is the probability that the variable takes a value less than or equal to x.
