Latent Class Analysis
Latent class analysis is a technique for forming segments (groups) from data. It is essentially a sophisticated (better) version of cluster analysis.
In Displayr, latent class analyses are run by selecting Anything > Advanced Analysis > Cluster > Latent Class Analysis.
Detailed technical information can be found on the Q Wiki. The two programs are identical, except that Q can analyze more data and has more advanced options.
Identify groups of similar observations (e.g. segments of people that have similar answers to the survey questions).
