Key Points NORMSINV is an Excel function used along with normal distributions. It allows you to conduct calculations faster ...

Cumulative probability distribution. A function that shows the probability that the random variable will attain a value less than or equal to each value that the random variable can take on.

Probability distributions are characterized as either discrete or continuous, and as working as either a probability density function, or a cumulative distribution. Discrete vs. Continuous ...

Probability distributions can also be used to create cumulative distribution functions (CDFs) that add up the probability of occurrences cumulatively. They always start at zero and end at 100%.

The variance v(a i) of the cumulative probability estimate a i =1-R i is computed using the exact variance method of Nelson (1990 pp. 150-151).. If no right censoring has occurred before t i, then a i ...
