The data file Britain Sick Leave shows data from Great Britain on the days of sick leave per person (Y), unemployment rate (X1), ratio of benefits to earnings (X2), and the real wage rate (X3). Estimate the model
log yt = β0 + β1 log x1t + β2 log x2t + β3 log x3t + εt
and write a report on your findings. Include in your analysis a check on the possibility of autocorrelated errors and, if necessary, a correction for this problem.
