When you request a lognormal probability plot, you must specify the shape parameter for the lognormal distribution (see Table 9.13 for the equation). The value of must be positive, and typical values ...

Key Points Normality refers to how your data fits into a normal distribution. You can find out if your data is uniform by ...

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

Creating a Normal Probability-Probability Plot ... The distances between two holes cut into 50 steel sheets are measured and saved as values of the variable DISTANCE in the following data set: * data ...

The PDF is the probability that our random variable reaches a specific value ... Each outcome has a probability of about 16.67% (1/6). Our plot below shows the solid line ...

One of the most versatile regression diagnostic methods is to plot the residuals r i against the predictors (x i, r i) and the predicted values (ŷ i, r i) ().When noise assumptions are met, these ...

Using only data not included in the model, we find the relationship between the Actual Completion Percentage and Completion Probability is strong, with an r-squared value of 0.98.

The p-value won’t tell you whether the coin is fair, but it will tell you the probability that you’d get at least as many heads as you did if the coin was fair. That’s it — nothing more.
