How can I test for autoregressive residual terms in a fixed effects panel Poisson model?

I have panel data for counts of new firms in different regions for six years. I am estimating a static poisson regression with multiplicative fixed effects$^*$; I have also tried to estimate a dynamic ...

What is being meant by "cohort-specific fixed effect for each state of birth" in Card&Krueger(1992)? What does the following equation mean?

I am referring to this paper on school quality and returns to schooling. The econometric specification has been described by eqn (1) on page 4. The authors have taken "cohort specific fixed ...

Modeling GARCH in R with other factors

I am new to GARCH model. I want to build a GARCH-in-mean model with the following forms $$r_t = \mu + \lambda \cdot h_t + \sum_{i=1}^n \alpha_i \cdot X_{i}(t) + \epsilon_t$$ where $\epsilon_t$ ...

Kleibergen Paap F-statistic

I have commonly seen references to a Kleibergen and Paap F-statistic. In their paper, I see a derivation of a chi-squared statistic, but don't see any references to the F-distribution or F-stat. In ...

AR(q) Strongly Stationary

Consider an AR(q) process, $u_t$. If the roots of a characteristic polynomial are outside of the unit circle, the AR(q) process is weakly stationary. I've seen this proof that proceeds by showing the ...

Get empirical steady state moments for calibrating a DSGE model

I want to calibrate some parameters of my DSGE model so that in the steady state some variable ratios, that are present in data, are met. My question is, how do I get such ratios from time series ...

Help Finding Information on "Power Trends" or "Polynomial Trends"

I need to prove some facts about the asymptotic OLS estimator, $\hat{\delta}$ in model: $y_t = \alpha_t + \delta \cdot t^b + \epsilon_t$ where $\epsilon_t \sim iid(0,\sigma^2)$. I've looked at ...

Systematic measurement error in explanatory variable

In the classical errors-in-variables problem, we are looking at the effect of $x^*_i$ on $y$, but $x^*_i$ is misreported. We have observations $x_i = x^*_i +u_i$, where $u_i$ has zero mean mean, ...

SAS: How to do ARIMA procedure with structural break?

So it seems like my data has a structural break in it, using Box-Jenkins methodology and evaluation such as ADF test wont give appropriate forecasts/results if I do not correct for the structural ...

Forecast of ARMA-GARCH model in R

I managed to forecast a GARCH model yesterday and run a Monte Carlo simulation on R. Nevertheless, I can't do the same with an ARMA-GARCH. I tested 4 different method but without achieving an ARMA-...
