MATLAB: Random time series and regression models

econometricseconomylinear modelmathMATLABregressiontime seriesuniversity

Hi. I need to generate 2 time series. the first one with 7000 numbers and the second with 20000. The first one has to be normally distributed and the second log-normally. How do you do that?
After creating that, I have to get a regression model for both time series.
Please help!

You can use r = normrnd(mu,sigma,1,100) to generate 100 random numbers from a Gaussian distribution with mean mu and standard deviation sigma.
Likewise, see r = lognrnd(mu,sigma,1,100).
See documentation on regression for the next step.
