This book is aimed at all those who wish to discover how to analyze categorical data without getting immersed in complicated mathematics and without needing to wade through a large amount of prose. It is aimed at researchers with their own data ready to be analyzed and at students who would ...

Each new topic in categorical data analysis is illustrated with an example that readers can apply to their own sets of data. In many cases, R code is given and excerpts from the resulting output are presented. In the context of log-linear models for cross-tabulations, two specialties of th...
The process leading to partial classification with categorical data is sometimes nonrandom. A particular model accounting for incomplete data, which allows the probability of uncertain classification to depend on category identity, is utilized for an analysis of data obtained from a genetic study on ...
Data Descriptive statistics can be used on any type of data, including numerical data (like age, weight, and height) and categorical data (e.g. gender, race, occupation).Inferential statistics use random samples from a population and make assumptions about how the data are distributed and how...
Qualitative palettes are best used on categorical data with no inherent order or magnitude, such as “United States” or “Iceland” or “Germany” Diverging palettes are best used when you want to emphasize the mid-point as well as the high and low end. For instance, you might want to ...
Example 1: Convert Categorical Vector Object to NumericExample 1 illustrates how to convert a categorical vector to numeric in R.For this, we first have to create an example vector:x <- factor(c("cat_a", "cat_b", "cat_a", # Create categorical vector "cat_c", "cat_b", "cat_b"...

I have a dataset with categorical data with 31 levels. I want to show their distribution in a scatterplot with ggplot, but I want to place special emphasis on some of the datapoints, like the red circ... Macro Vim - expand multiple Verilog Bus ...
In this lesson, we apply regression analysis to some fictitious data, and we show how to interpret the results of our analysis. Note: Regression computations are usually handled by a software package or a graphing calculator. For this example, however, we will do the computations "manually", ...
