Using this type of quantile function to find the confidence coefficient of a random sample helps us better approximate the true value, which we can further narrow down byperforming linear regression and testingthe alternative hypothesis. Linear regression will give us acorrelationcoefficient, and by c...

To perform attest, you calculatetfor the sample and compare it to a critical value. To find the right critical value, you need to use theStudent’stdistributionwith the appropriate degrees of freedom. The null distribution of Student’stchanges with the degrees of freedom: ...
If you create bootstrapped confidence intervals for the ERF, two additional fields will be created containing the number of times the observation was selected in a bootstrap sample and the number of times that the observation was included in a bootstrap sample that attained balance. It...
There is currently no consensus on how to assess confidence in the coefficients from a GWR model. While t-tests have been used to base an inference on whether the estimated value of coefficients is significantly different than zero, the validity of this approach is still an area o...
The magnitudes of coefficients are comparable to my baseline results in Table6. However, the confidence intervals are relatively wide due to low power, as the analysis only includes observations surrounding the initial performance disclosure. When I extend the analysis to the 12-month post-disseminati...
First, we try to find the differences in travel behavior in the pre and post COVID-19 period. Second, we consider the user heterogeneity and study the preference of different groups to the customized bus services. Third, we provide constructive suggestions for managing the significant changes in...
