The population regression function prf is a description of the model that is thought to be generating the actual data and it represents the true relationship between the variables. The prf embodies the true values of �1 and �2, and is expressed as: where yi is the actual value obtained by adding the error term ui or as where e y may be regarded as the average or expected value of y for a given value of x.

The population may be either finite or infinite, while a sample is a selection of just some items from the population. In general either all of the observations for the entire population will not be available, or they may be so many in number that it is infeasible to work with them, in which case a sample of data is taken for analysis. Brooks, 2002, pg.112 the sample regression function srf it allows us to calculate the estimated value of y for a given value of x. The following diagram illustrates a possible combination of parameters, for simplicity we assume that all parameters are positive: 3. 20% consider the following regression 50 0.1 se 10.7509 t 18.73 r2 0.935 n 17 fill in the missing numbers and establish a 95% confidence interval for �2.

Would you reject the null hypothesis that the true �2 is zero at ? 5%? tell whether you are using a one tailed or two tailed test and why. To find the t value for �1 the following formula will be used: assuming �2 to be 0 we obtain: for finding the standard error of �2 we rearrange the formula to keep the standard error non negative the assumption that t value for �2 is negative is made. In order to establish a 95% confidence interval we need to use the following formula: where ? 5% n 2 15 replacing these values in the above formula we obtain we can state that there is 95% chance that the value of �2 is in this interval 0.14 0.0886. In other words in 95 cases out of 100 the true �2 value will fall within the interval. Despite the fact that r2, the measure of goodness of fit of a regression, is different in the two models we cannot state that one is preferable to the other because the controlled variables are different in models a and b, therefore we cannot compare the r2 values directly. 30% you are given the following data based on 20 pairs of observations on y and x. Assuming all the assumptions of clrm are fulfilled, obtain a based on the assumptions of the classical linear regression model we can write the general form of the function: for calculating the regression coefficients we use: mean of y is: mean of x is: b standard error of 5.b.1 gujarati, pg.

58 5.b.2 now we combine 5.b.2 with 5.b.1: c establish 95% confidence interval for the parameters n 2 20 2 18 ? 5% d on the basis of the confidence intervals established in c , can you reject the hypothesis that �2 is statistically significant? confidence interval established for �2. This confidence interval 0.5216 0.7317 doesn't contain zero, therefore �2 is statistically significant or is statistically different from zero. That is why we cannot reject the hypothesis of �2 being statistically significant. The appropriate type of hypothesis in this case is the left tail test: null hypothesis h0:�2 gt 1 alternative hypothesis h1:�2?1 decision rule 7.4667 lt 1.734 true gt we reject the null hypothesis that �2 gt 1.

The above preview is unformatted text econometrics coursework assignment 2 for this assignment, use the dataset eaef_as2.dta, which has 1200 observations, and is downloadable from syd. The data contain information on wages and characteristics of workers in united states, in 2002. It includes a variable catgov which indicates whether the person works a build a model to estimate how much more or less workers on average earn when they work for government as opposed to private sector, holding the other determinants of wages constant.

Do this by expanding the model in a to test whether ability asvabc and years of schooling s have a larger effect on earnings in government than in the private sector. 20% it may be sensible to use a do file to avoid retyping the regression commands multiple times. Example: tabulate female catgov to look up how a command works, use help, such as help regress. Are the key assumptions of ols holding note that some of them cant be directly tested ? study the dataset and variables and think what you can and cant do with it.
