This component shows the (cumulative) customer count or churn rate by time and time-based cohort. Cohorts are used to group individual records by the characteristics that they share, which is their starting time in this case. Analysis of cohorts reveals trends and patterns that could not be identified from the individual records. A time-based cohort for each ID is defined based on the first time when the ID appears in the data. Four types of churn analysis are possible: 1. The cumulative customer count by time and time-based cohort (stacked area chart) 1. The cumulative churn rate by time and time-based cohort (stacked area chart) 2. The customer count in each time-based cohort over time (line plot) 2. The churn rate in each time-based cohort over time (line plot) Required extensions: - KNIME Expressions (https://hub.knime.com/knime/extensions/org.knime.features.expressions/latest) - KNIME Plotly (https://hub.knime.com/knime/extensions/org.knime.features.js.plotly/latest) - KNIME Math Expression (JEP) (https://hub.knime.com/knime/extensions/org.knime.features.ext.jep/latest) - KNIME Quick Forms (https://hub.knime.com/knime/extensions/org.knime.features.js.quickforms/latest)
