Life Data Analysis - LDA

Life Data Analysis module was developed to analyze any type of continuous random variable data, including, time to failure, time to repair, production, costs, among others. You will have access to state of the art mathematical algorithms to statistically analyze your data, supporting your decisions in product development, asset management, maintenance activities and more.
