Answer: coefficient of determination Component of time series in all but Answer: panel regression Poisson distribution is used toâ€|â€| Answer: determine the probability of designated number of success Partial correlation coefficient between Y and X1, holding X2 constant can be presented as Answer: ryx1 x2 In statistics, stating level of confidence as 95% confidence level means â€|â€|.. Answer: it is about stating a probability that the estimate is right at 95% measures how a variable dispersed around the population mean Answer: standard deviation of population What does partial correlation measures? Answer: measures the correlation between a dependent variable and one independent variable holding other variables constant If the variance of a population is denoted as Var P and n = 100, P = 0.4, what is the standard error? Answer: 0.04 Standard error is â€|. Answer: defined as the square root of population variance x1 and x2 are the means of two samples drawn from population. Specify the sampling distribution of the differenc of two means. Answer: (x1 - x2) = up1 - up2 In a sampling distribution of two means, if P1 = (20,40) and P2 = (30,60), what is Up1 + p2? Answer: 77.5 State the null hypothesis as used in ANOVA Answer: hO: u1= u2 = u3 =â€|.=un Is the assumption \ Answer: yes the formular for calculating intercept multiple regression Answer: y = a - bx1 - bx2 In testing overall significance of a multiple regression model, if n=8, k=3, find the degree of freedom and the value of Ftab at 5% level of significance Answer: df= 2,5 and ftab = 5.79 The total variation in two-way ANOVA is divided intoâ€|â€|â€! Answer: variation between treatment, variation between block and residual variation is a continous variable that correlate with the dependent variable Answer: covariate In a two way ANOVA, set of observation is classified as Answer: 2 factor Email: bbcnoun@gmail.com Whatsapp: 08131667008
