Multimodal Analysis In life data analysis, the goal is often to fit a good model to the data set. Once a good model has been fitted to the data, other analyses and predictions can be made. Life data can be represented visually on a probability plot. Ideally, the data points on the probability plot should fall in a straight line, indicating a good fit to the specific distribution. If the data points do not fall in a straight line, this is an indication that the chosen distribution is not a good choice to model the data, and another distribution should be chosen. One of the potential reasons for the inability to fit a straight line to the data is the presence of multiple failure modes. Multimodal data sets can often be recognized by the pattern evident on the probability plot. If the points on the plot appear to have a distinct "dogleg," or seem as if they could be modeled by two straight lines of different slopes, this may be indicative of a multimodal data set. In this article, we take a look at methods for analyzing multimodal data sets. To read more, see
