Choose the correct answer from the options given below:

(B), (C) and (D) only

The correct answer is Option (3) → (B), (C) and (D) only

(A) Time series analysis does not help to understand the behavior of a variable in the past.

Time series analysis is mainly used to study past behaviour, hence this statement is false.

False

(B) Time series predict the future behavior of variable.

Forecasting future values is one of the important objectives of time series analysis.

True

(C) Time series helps to plan future operations.

Planning and decision making are based on time series forecasts.

True

(D) The main aim of the time series analysis is to derive conclusions after arranging the time series in a systematic manner.

Systematic arrangement and drawing conclusions are core objectives of time series analysis.

True

The correct options are (B), (C) and (D).
