beta

1. Beta significance level in one model the same as the R-squared-change significance

I am very new to statistics, so apologies in advance if I have not explained this clearly. I have run two types of linear regression: - The first contains 4 independent variables, all entered at the same time. - The second uses "blocks" to enter 3 of the independent variables in the first...
2. P

binomial distribution problem, calculating probability from a B(p,q) distribution

Hello everyone, I have been trying to solve this Beta distribution problem for quite some time without success. I can get as far as getting the 20 value, but I just cannot tell how the f(x)dx = .3672 is obtained. Underneath is a short description of the problem and on attachment the approach...
3. Beta NO Intercept purpose

Hey guys, What would a Beta with NO intercept tell me about a time series model?
4. Rank Coefficients

Is there a way to rank the relative importance of correlation coefficients?
5. [Stata] How to Get the Beta Coefficient as a Variable using Stata

After regressing by gvkey: lag1 lag2 I get 815 tables with a beta coefficient included. But I am only interested in getting these betas in a list for further use. Thx for your reaction in advance!
6. Help with the Beta Distribtuion

Background: I'm currently trying to learn how to use Bayesian Analysis for split testing two sets of binomial data. (Web analytics, Multi-Armed Bandit approach, etc). The Beta distribution kept coming up in this research, so Im trying to understand and apply it better. So, the best...
7. Hypothesis Testing - finding the power and beta!

A medicine dispensing machine is designed to discharge on average at least 8ml of medicine per dose with a standard deviation of 0.2ml. The amount of medicine per dose is normally distributed. a) If you select a random sample of 16 doses and you are willing to have an (alpha or significance...
8. Statistics Final Exam Question

Due to some gray area in a TA's grading, I am going to review my statistics final with my professor on Friday. There's some possibility of a grade change. One of the questions I'm most anxious about, the final question, went essentially like this: "Tommy finds a deck of cards, but he is not...
9. Plotting regression coefficient over time

Dear everyone, Hi everyone, I am relatively new to stata and would deeply appreciate your help on this. I am trying to plot my main beta coefficient over time but am not really sure as to which commands I should use. My main dv and iv are fdi inflow and political tension and my data covers...
10. Trouble standardizing regression slopes

Dear readers, Hopefully you can help me with the following problem. I am using meta-analytic software to perform a meta-analysis. When I perform meta-regression in this program, results only show unstandardized slopes (B). To allow comparison of my predictor X (in days) with others (from...
