Summary of thesis this thesis is an account of some aspects of time series analysis for directional data (or, more strictly, circular data), which is an almost totally unexplored area of. Time series analysis is a statistical technique that deals with time series data, or trend analysis time series data means that data is in a series of particular time periods or intervals the data is considered in three types: time series data: a set of observations on the values that a.

These models have been extensively used in practice for forecasting economic time series, inventory and sales modeling (bajwa, saeed, saeed, & zakria, 2000) the standard approach for building a model to forecast future values of a time series uses the analysis of the autocorrelation function and partial-autocorrelation function (egan w j, 2008.
