The total probability under the curve is 1
WebDec 6, 2011 · The total area under a normal distribution is not infinite. The total area under a normal distribution is a continuous value between any 2 given values. The function of a normal distribution is actually defined such that it must have a fixed value. For the "standard normal distribution" where μ=0 and σ=1, the area under the curve is equal to 1. WebThe likelihood function (often simply called the likelihood) is the joint probability of the observed data viewed as a function of the parameters of a statistical model.. In maximum likelihood estimation, the arg max of the likelihood function serves as a point estimate for , while the Fisher information (often approximated by the likelihood's Hessian matrix) …

WebAll scores were summed up to obtain the total score. A probability equation was developed by applying linear regression analysis on the total score. The prediction model had good diagnostic performance with an area under the receiver operating characteristic curve =0.833 (95% confidence interval =0.809–0.857). WebBecause most of the density is less than $1$, the curve has to rise higher than $1$ in order to have a total area of $1$ as required for all probability distributions. This density (for a beta distribution with parameters $1/2, 1/10$) becomes infinite at $0$ and at $1$. The total area still is finite (and equals $1$)!
