aTable 3 reports three different estimates of the parameters in specification (1): the pooled ordinary least squares (OLS), the between, and the fixed-effects (within) models. Though each model is based on different assumptions, all three produce an estimate of that is positive and high...
aIn parallel with the previous aggregated results, Table 5 reports the results of the pooled OLS, the between, and the fixed-effects estimators. The results of the pooled OLS and between models are again quite similar. With the exception of diversity, all dimension-specific CSI coefficients tha...
Methods: We examined medical care utilization and expenditure of outpatient Korean medicine using panel fixed effects model to remove selection bias. Then we compared it with pooled ordinary least square (OLS) model. This study used Korea Health Panel data, which provides accurate information on ...
Subject: Re: st: RE: pooled ols interpretation, thanks Actually puting dummies for year is a good idea. What that does is eliminate the effects of any shocks that affect all cases. Suppose, for example, you were analyzing U.S. state level data and the national business cycle or national...
Tests of the assumptions of OLS indicate the presence of heterescedasticity and autocorrelation but the absence of unacceptible levels of multicollinearity. Based on the results of the Hausman test, a fixed effect regression analysis is used to test the model. In order to test the robustness of...
fixed effects, is that they account for any such unmeasured state-level characteristics that remain constant over time and may influence outcomes. Univariate and bivariate analyses were conducted to determine variable means and relationships between cigarette price, age and smoking, and similarly for ...
13.48 between studies ¼ 0.011), whereas for laryngeal cancer we reported the fixed-effects ones (P-value for heterogeneity between studies ¼ 0.464). Vitamin E intake was inversely related to oral and pharyngeal cancer, with an OR of 0.59 (95% CI: 0.49–0.71) for the fifth quintile ...
In all the analyses described, when the P-value for heterogeneity between studies was <0.1, we used a mixed-effects modelling approach and replaced in the tables the fixed-effects ORs and CIs with the corresponding mixed-effects ones. We derived those estimates specifying a random intercept-rando...
A fixed-effects model was designated to compute the pooled OR for each individual study in cases where the I2 index < 50% (p-value ≥ 0.10) [32], while a random-effects model was applied to ascer- tain within-study inaccuracies if the heterogeneity was achieved with the I2 index > ...
Since it is plausible that the data exhibits short-run dynamics as well as nonzero fixed effects, the individual tests are conducted on prewhitened data that are subsequently centered by means of first observations as we expect inflation rates to have nonzero means under stationarity. The Schwarz...
