2. Missing Outlier Data. Normal probability plots don’t tell you how many outliers there are or where they are. You can use them to see whether or not there are any outliers in your data set ...

Key Points A Box-Cox Power Transformation allows you to transform data to match a normal distribution. It is not a guarantee ...

Non-normal distributions have fatter tails than a bell curve (normal probability) distribution. A fatter tail skews negative signals to investors that there is a greater probability of negative ...

A bell curve is a graph used to visualize the distribution of a set of chosen values across a specified group that tend to have central, normal values that peak, with low and high extremes ...

Normal distribution cannot be used to model stock prices because it has a negative side, and stock prices cannot fall below zero. Another similar use of the lognormal distribution is with the ...

A LARGE part of statistical theory is based on the assumption that measurements are distributed in normal probability curves and that the variance is constant. The normal curve was discovered by ...
