QQPlot Quantile-quantile (QQ) plots are an exploratory tool used to assess the similarity between the distribution of one numeric variable and a normal distribution, or between the distributions of two numeric variables. Scatter Scatter plots visualize the relationship between two numeric variables, wh...
Plotting quantile regression coefficients Converting a continuous variable to a discrete value for regression I need help to add the title to a MCA factor map plot Degree of vertex Plot() does only show Residuals vs. Fitted, but not other diagnostic plots; par(mfrow=c(2,2)) alrea...
QUANTILE REGRESSION command CRITERIA subcommand TheQUANTILEkeyword now provides support for a grid of quantiles (connected by the keywordsTOandBY). The quantile grid can be mixed with other quantiles, and can be placed anywhere.For more information, seeCRITERIA Subcommand (QUANTILE REGRESSION command)...

The quantile 50% represents the median, and one of the most common quantiles is called the quartile, which splits the data into four parts of 25% each. However, the position measurements are not sufficient to characterize the distribution of data, and therefore we need to analyze dispersion ...
This residual indicates that the model underpredicted the individual’s income by $2,000. Understanding and analyzing residuals is essential for validating regression models and ensuring accurate and reliable results. By examining residuals, analysts can improve model fit, detect violations of assumptions...
deviation. Although the figure on the left does not reveal much of the differences between these distributions' tails, the figure on the right gives a clearer view by plotting the quantiles of the distributions against each other. This technique is known as a quantile-quantile plot, or Q-Q ...
Quantile regression. Ridge regression. Structural equation modeling. Tobit regression. Each specific approach can be applied to different tasks or data analysis objectives. For example, HLM -- also called multilevel modeling -- is a type of linear model intended to handle nested or hierarchical data...
Figure 5. Spatial deviation after a rediscretization of factor k. In (a), the box-plot has whiskers at the 99%99% quantile; in (b) it has no whiskers. Figure 6 shows the speed difference after rediscretization. In contrast to path uncertainty, speed difference increases in an approximatel...
