Missing not at random data is a more serious issue and in this case it might be wise to check the data gathering process further and try to understand why the information is missing. Data analysis must occur concurrently with data collection and comprises an ongoing process of ‘testing the fit’ between the data collected and analysis. We can say, clustering analysis is more about discovery than a prediction. Initial Data Analysis (infert dataset) Initial analysis is a very important step that should always be performed prior to analysing the data we are working with. Data analysis is a process of inspecting, cleansing, transforming, and modeling data with the goal of discovering useful information, informing conclusions, and supporting decision-making.
