Step 1
Cyclic trend is regularly recurring pattern. In this type of trend given scenario happening again and again at specific interval of time.
Generally we see this type of trends in business cycle where there is sudden growth and fall in sales for specific time of year.
Clustering : The process of clustering involves grouping the population or data points into a number of groups so that the data points within each group are more similar to one another than the data points within
other groups.
Secular trend :
A secular trend is an indication of an ongoing pattern over an given period of time.
It is a statistical tool that is simple to spot and is unaffected by
seasonal or cyclical effects.
Epidemic curve:
A statistical graph called an epidemic curve is used in
epidemiology to show how a disease outbreak begins to spread.
It can assist in determining the disease's origin of transmission.
It might also display the severity of the illness.
It also represents that if there are any outliers or there are any cluster.
It shows their trend over time, their incubation period.
