does rolling data result in a stationary process? why is a moving average not considered a stationary process are health care metrics stationary what is the rolling 12 month period used for is time series data a stationary process when do you aggregate data what is rolling 12-month data which method best reflects the seasonality of health care data? when to reaggregate time series is rolling 12 month aggregates stationary is rolling 12 months aggregation stationary when are time series time series is lma a stationary measure is rolling12 month aggregate stationary why is time series aggregate data not stationary? which metrics are pre-aggregated into non stationary rolling periods? is r rolling 12 months stationary why is a rolling 12 month aggregate not stationary? how long is rolling 12 month lag in health care why do i need to aggregate time and data
