1.1 Background of the Study
The corona virus disease 19 (COVID-19) is a highly transmittable and pathogenic viral infection caused by severe acute respiratory syndrome corona virus 2 (SARS-CoV-2), which emerged in Wuhan, China and spread around the world. Genomic analysis revealed that SARS-CoV-2 is phylogenetically related to severe acute respiratory syndrome-like (SARS-like) bat viruses; therefore bats could be the possible primary reservoir. The intermediate source of origin and transfer to humans is not known, however, the rapid human to human transfer has been confirmed widely. There is no clinically approved antiviral drug or vaccine available to be used against COVID-19. However, few broad-spectrum antiviral drugs have been evaluated against COVID-19 in clinical trials, resulted in clinical recovery. This research centers on the corona virus evaluation and forecasting. Forecasting is a means of predicting what is going to happen in the future, next month, year, decade e.t.c. Accurate forecasting requires high quality data, application of the application of the appropriate forecasting technique and knowledge interpretation. The accuracy of such forecasts depends in large measure on the degree to which the past is a good guide to the future (Studemund, 1995).
Prior to building a forecast model, the first step is to clearly understand the problem in order to establish the forecast range and objective (Al-Alawi, 1996). Therefore, the four steps of forecasting are:-
The research work on covid19 forecasting and evaluation will focus on the use of linear regression model to forecast covid 19 pandemic in Nigeria. It can be highly beneficial for government to develop a system to forecast future values of some important metrics such as possible infections of its citizens, or variables that describes the pandemic status.
There are different methods of making forecasts, but they all fall into two categories. Casual methods and time series method, (Andrew Gellant, 2013). Linear regression is time series methods that use basic statistics to project future values for a target variable. All organizations, big or small have at their disposal men, machines and materials, the supply of which may be limited, (Gupta and Hiza 2008). If the supply of these resources were unlimited, the need for managerial tool like linear programming would not rise at all. Supply of sources being limited, the management must find the best ablation of its resources in order to maximum the profit or minimize the loss or utilize the production capacity to the maximum. However, this involves a number of problems which can be overcome by quantitative methods, particularly the linear programming in different financial institutions.
1.2 Statement of the Problem
There are many problems concerned with forecasting and evaluation of corona virus, such as
1.3 Significance of Study
This research work will provide a more benefits to users such as:
1.4 Aims and Objectives Of Study
The aim of this research is the design and implementation of a covid 19 forecasting and evaluation system.
The specific objectives are:
1.5 Contributions to IT Practice
This project work “Design and Implementation of an expert system for evaluation and forecasting of covid 19” will certainly foster the use of computerized systems in disease control. It will produce a system that will be able to eradicate the problem of manual evaluation of patients. This expert system will also give room to further expansion through time making it possible to produce a more fastest and accurate means of forecasting future pandemics.
1.6 Scope of Study
This research work is to develop a system capable of evaluating and forecasting spread of corona virus pandemic on a daily basis using an expert system.
This system will not incorporate in its development all the models use for forecasting but will focus only on the aforementioned models and functionalities.
1.7 Assumptions
Assumption is any project factor that is considered to be true, real, or certain without empirical proof or demonstration. Realistically speaking, it is impossible to plan a project without making a few assumptions (Boogaard, 2020).
The following assumptions were made in the course of this study
