WebThe NORM.DIST function returns values for the normal probability density function (PDF) and the normal cumulative distribution function (CDF). For example, NORM.DIST (5,3,2,TRUE) returns the output 0.841 which corresponds to the area to the left of 5 under the bell-shaped curve described by a mean of 3 and a standard deviation of 2. Webp = normcdf (x,mu,sigma) returns the cdf of the normal distribution with mean mu and standard deviation sigma, evaluated at the values in x. example. [p,pLo,pUp] = normcdf (x,mu,sigma,pCov) also returns the 95% confidence bounds [ pLo, pUp] of p when mu and sigma are estimates. pCov is the covariance matrix of the estimated parameters.
