Normal distribution, also known as Gaussian distribution, is the most important statistical probability distribution for independent random variables. Most researchers will recognize it as the familiar bell-shaped curve present in statistical reports. Normal distributions are appropriate for continuous variables...
As we’ve seen above, the normal distribution has many different shapes depending on the parameter values. However, the standard normal distribution is a special case of the normal distribution where the mean is zero and the standard deviation is 1. This distribution is also known as the Z-di...

A Lognormal Distribution is defined as a probability distribution that describes the random shadowing effects in signal propagation, where the signal power follows a Rayleigh distribution but its mean square value is lognormal in dBm with a specific variance. ...

Normal distribution, also known as the Gaussian distribution, is aprobability distributionthat is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean. The normal distribution appears as a "bell curve" when graphed. Key Takeaways ...
