Measuring Test The Stationary Of Data Essay - 1787 Words

Chapter 4 Results 4.1 Test the stationary of data In order to avoid spurious regression, we use ADF test to examine whether the individual economic variables in the model is stationary or not. The original order ADF test was done on the growth of consumer price index (CPI). And the result shows that the P value is 0.031, which is smaller than 0.05, so we reject the null hypothesis and accept the alternative hypothesis that CPI growth i.e. Inflation has no unit root. Inflation is proved to be stationary. Table 1: ADF test for inflation Then test the stationary of output gap. I have done the same test with output gap. The result shows the P value of original order ADF test of output gap is 0.0408, which is still smaller than 0.05, so we reject the null hypothesis and accept the alternative hypothesis that the output sequence has no unit root, thus it is stationary. Table 2: ADF test for output gap Next, text the stationary of money supply growth. The results show that the p value of money supply growth ADF test is also equal to zero, which is same as that of output gap, so we reject null hypothesis and confirm that the data of money supply growth is stationary. Table 3: ADF test for growth of money supply Finally, test the last economic variables: cyclically adjusted fiscal deficit (as percentage of GDP). The results shows that the p value of first order stationary is equal to zero, so it can be inferred that the data has no unit root and is a stationary sequence.

In summary, measuring BP is an important parameter used diagnostically as well as prognostically. BP measurement not only helps to prescribe the exercise regime and gauge exercise intensity but also help maintain safe and efficacious exercise. On the other hand, measuring BP during exercise might act as a distraction disturbing the steady state exercise intensity desired for optimal exercise-inducedRead MoreThe Effects of Environmental Factors on the Absorbance of Escherichia Coli1674 Words   |  7 PagesEscherichia coli the greatest. It is known that these abiotic factors affect the rate of growth the greatest if they remain at the correct conditions for living. Escherichia coli and other bacteria will go through four phases; a lag phase, log phase, stationary phase, and a death phase. In the lag phase, the bacteria reproduce fairly slowly, as they are preparing for the rapid division (Doyle). In this lag phase the bacteria is making fats and proteins which will jump-start the log phase (Doyle). TheRead MoreAbsolute Best Model For Forecasting1696 Words   |  7 Pagesto find the best possible model for forecasting. I will use a series of tests both visual and statistical to find the absolute best model for forecasting the data set. The forecast will be made for the conglomerate Wal-Mart. I start my test by taking the time series plot graph of the data. This indicates whether the data has a seasonal or quarterly trend, and if there is a time trend. I also run a trend analysis on the data set. I compare the graphs through trend analysis, and choose the graph withRead MoreCooling drinks912 Words   |  4 Pageswater The molecules of H20 behave differently in water than in ice. In water they are floating around freely and in ice they are stationary, they only vibrate slowly. This is because they don’t have enough energy to break their intermolecular bonds. So in order to melt ice you need to add energy to give the molecules kinetic energy to move around, becoming less stationary. If enough energy is given to the molecules they break the intermolecular bonds and the ice melts to ice. 4) Why is ice more effectiveRead MoreResearch Report On Data Collection3363 Words   |  14 Pagesinclude the data collection, data source, variables, research design, theoretical research framework, sampling design, test consideration for data analysis, hypotheses statement and conclusion. 3.2 DATA COLLECTION Data collection involves the process of gathering information and data either from primary or secondary data. In this study only secondary data is used. 3.2.1 Secondary Data Secondary data refers to the statistical material which is obtained from someone else records. Secondary data helpedRead MoreWhy The Enzyme Is Understanding Their Properties Essay1683 Words   |  7 PagesAn important aspect of studying proteins is understanding their properties. The hypothesis of this experiment aimed to test whether the enzyme in question, N-acetyl-ÃŽ ²-D-Hexosaminidase, has an overall negative charge and will elute from the DEAE column in the first protein peak. The experiment was done in two parts. The absorbance values obtained from conducting the Lowry protein assay were used to extrapolate the total amount of protein and calculate the concentration of the protein. The total amountRead MoreJohn Maynard Keynes Absolute Income Hypothesis1481 Words   |  6 Pagescombined with the Wald Test, with controls for variances that a simple version of DID/Wald would not be able to capture. The first of their results that can be of importance to consumption is that stud ents with student loan debt were more likely to take higher-salary jobs over lower paying or â€Å"public interest† positions, which would result in higher pre-debt servicing disposable incomes. The claim that those with student loan debts are not life-cycle agents stems from data about the pledges studentsRead MoreA Relationship Between Shoulder Flexion Angle And Mobility Measured Through A Tug Test859 Words   |  4 Pagesmeasured by a Timed Up and Go (TUG) test. Identifying a relationship between these variables may aid assessment of patient’s mobility. The null hypothesis was that there is no relationship between average knee flexion angle and TUG score. The alternative hypothesis was that there is a relationship between average knee flexion angle and TUG score. Aim: To investigate whether there is a relationship between average knee flexion angle and mobility measured through a TUG test to aid assessment of knee OA patient’sRead MoreMental Rotation of Images1432 Words   |  6 Pagesand asked to make judgement, as quickly as possible, as to whether the two shapes presented were the same or mirror images. Two different shapes were used in this experiment, each given as often as the other. During each trial one shape remained stationary and the other was rotated with varying amounts of 0, 60, 120, and 180 degrees. As the angle of rotation increased reaction times were calculated to see if this had any baring on the speed of the reaction. As predicted, reaction times increasedRead More Mental Rotation Of Images Essay1439 Words   |  6 Pagesand asked to make judgement, as quickly as possible, as to whether the two shapes presented were the same or mirror images.
