Question

[1] A stochastic process or time series process refers to a sequence of random variables indexed by time. sequence of variables that can take fixed qualitative values. sequence of random variables that can take binary values only. sequence of random variables estimated at the same point of time. od [2] The sample size for a time series data set is the number of a. variables being measured. time periods over which we observe the variables of interest less the number of variables being measured. time periods over which we observe the variables of interest plus the number of variables being measured. time periods over which we observe the variables of interest. c. d.

Answer 1

1. A stochastic process or time sucies pouss refers to a. Any la) sequenue of random res Lomreet answve. variables indexed by time. b), lo and (d) .ate as in (6) it talks qualitation value but or rondom thing so numrect obtiens about variables taking tixed stochastic means. non. - fixed (b) is incorrect. ( सम tam W Shachlhata mo sequenu of sandom only is also incorrect it talks about randon take time period into variables take binary values option becaux although variables but does not considereation, d) dequence of random variables estimated at the same point of time. is also incorrect option because it says rondom does not take into consideration one time analysis of panelom voiable rather it analyse random variable at fixed point of time. which is not the property of time dueren analysis. So option (o) con botter sandom is correct option as it over time analysis of coverables at take into sequence of

The sample size for a time series date set is the number of Ane (d) - lime periods one which of interest (correct ansure) we obsou the variables rest (a), (b) and to are incomect options. (a) variables being measures is incorrect because the date set with no of variables being measwid is not a sample size of time wies anda. as here we do over time analysis of interest variables esimilarly (b) and w are also incorrect.
