Latent class analysis

Imagine if you had a big bucket of different colored candies like red, green, blue and yellow. If someone asked you to sort the candies by their color, you would group them together based on their color. However, what if the candies have multiple colors and it's difficult to sort them into just one group? This is where latent class analysis comes in!

Latent class analysis is like sorting the candies into smaller groups based on different characteristics like their shape, size, or flavor. Instead of looking at just one characteristic like color, latent class analysis looks at many different characteristics to group them together into smaller groups based on their similarities.

Let's use an example of a survey. Imagine if you gave a survey to people asking them about their favorite type of candy. Instead of just looking at one answer (like "I like chocolate"), latent class analysis can group together people who have similar answers and behaviors. For example, it can group people who like chocolate, caramel, and peanuts together as a "chocolate lovers" group. It can then group people who like sour, fruity, and chewy candies together as a "sour candy lovers" group.

Latent class analysis can be helpful in understanding different groups within a larger population, such as customer segments for a business or different types of patients in a healthcare setting. By understanding these different groups, businesses and healthcare providers can tailor their products and services to better meet the needs and preferences of each group.
