In addition to this, E-views allows the work files or the database from MS Excel, SAS, SPSS, STATA and Text file. Performing data analysis in E-views is easier to understand as all the necessary statistical modelling can be performed by estimating the regression equation.
#Panel regression eviews series#
0.E- Views offer an impressive toolkit that involves the series or the group of series that allows estimating panel data analysis ranging from the simplest to the complex types. You can calculate the probability of F >229.1 for 1 and 148 df, which comes to approx. The F – statistic is calculated as below – The test is similar to the t-test or other tests we do for the hypothesis. F – statistic:į test tells the goodness of fit of a regression. The maximum possible value of R 2 can be 1, means the larger the R 2 value better the regression. Here, 66.9 % variation in Y can be explained by X. R 2 is the coefficient of determination that tells us that how much percentage variation independent variable can be explained by independent variable. Since 0 does not lie in any of the intervals so we will reject the null hypothesis. While calculating p values we rejected the null hypothesis we can see same in C.I as well. 5% is the standard significance level (∝) at which C.I’s are made.Ĭ.I for B 1 is ( b 1 – t ∝/2 s.e(b 1), b 1 + t ∝/2 s.e(b 1) ) The confidence interval approach is one of them. There are many approaches to test the hypothesis, including the p-value approach mentioned above. If you know about significance levels then you can see that we can reject the null hypothesis at almost every significance level. This is not exactly 0, but since we have very large t statistics (-12.458 and 17.296) p-value will be approximately 0. In the summary table, we can see that P-value for both parameters is equal to 0. In theory, we read that p-value is the probability of obtaining the t statistics at least as contradictory to H 0 as calculated from assuming that the null hypothesis is true. And σ 2 is equal to RSS( Residual Sum Of Square i.e ∑e i 2 ). Here, σ 2 is the Standard error of regression (SER). Standard error shows the sampling variability of these parameters. Standard error of parameters: Standard error is also called the standard deviation. If you are familiar with derivatives then you can relate it as the rate of change of Y with respect to X. In regression we omits some independent variables that do not have much impact on the dependent variable, the intercept tells the average value of these omitted variables and noise present in model.Ĭoefficient term: The coefficient term tells the change in Y for a unit change in X i.e if X rises by 1 unit then Y rises by 0.7529. From regression line (eq…1) the intercept is -3.002. of observations) and K = number of variables + 1 Df of model:Ĭonstant term: The constant terms is the intercept of the regression line. Degree of freedom(df) of residuals:ĭegree of freedom is the number of independent observations on the basis of which the sum of squares is calculated. Number of observations: The number of observation is the size of our sample, i.e. The principle of OLS is to minimize the square of errors ( ∑e i 2). This model gives best approximate of true population regression line. Model: The method of Ordinary Least Squares(OLS) is most widely used model due to its efficiency. In this regression analysis Y is our dependent variable because we want to analyse the effect of X on Y. Prob(Omnibus): 0.171 Jarque-Bera (JB): 3.589ĭependent variable: Dependent variable is one that is going to depend on other variables. The summary table of the regression is given below.
