I think that I have kind of figured out what it means. I think in this case, there will be only two models, rather than three of them if we ENTER the variables one by one. while, as you can see, it's part of the the other message that I have posted, what the question concerns is to analyze Model...

as I suggested, just run spss to see what are the differences between the two regressions. I do not have SPSS and never use it. It you are not sure, send me the results. I will go through with you. spsun1@yahoo.com

I am still thinking about the second question, as I think 22 is not correct, or we need to say that all other independent variables have to equal to zero. This is far beyond the mean plus 3 standard deviations. From statistics, 95% of the data should fall within mean + 2.86 x SD. Any...

you are fine: keep on thinking. you need to understand the theory and assumption etc behind the regression analysis. typing error: "everything should be ....every one percentage point..

yes. you need to state: other things being equal.. everything percentage point change in unemployment rate, the income penalty varies 1,573... the mean of unemployment rate is 1.525 and sd is 1.273, I think these would give you the information on the range of the data..

the second question could be answered as follows: the mean for the unemployment rate is 1.525 and sd is 1.273, so once the unemployment rate is greater than 2.58 or 3.??? times sd , the result would be not reliable. check the book for the value of the confidence level at 95 % and 99%.

the coefficient will tell you the impact. the income penalty (loss) will be -1,573 for per 1 percentag point increase in unemployment rate. The maximum unemployment rate should be 22 the constant 36,701/1573 = 22, please do the detailed calculation yourself. At this point the income will...

maybe not too many people here cab access SPSS. why not just run and see the results. e.g., how many coefficients you will get. y = a + b * x1 + c * x2 + d * x3 or y = a + b * x1 +c * x2 * x3 ????

0.34 =0.34 3.40E-01 =0.34 3.40E+08 =340000000 I copied from Excel.

I am sorry, I was worng. e and E are different. your Excel will tell you. E is in scientific format.

The above answer is not correct. e is 2.78.... For example, in the logrithem, Log based 10 and log base e are not the same.

Did you try using a good plunger? The rubber one is no good. The plastic (blue colour-at Home Depot) one is more effective. If it is because oil/fat, make sure using very hot water to rinse it after. I would definitely open the trap/pipe first.

If your toilet is working, it is likely the trap is blocked with oil or fat, etc. Like what I suggested, see whether you can open the drain pipe under the sink. clean-up from there. Otherwise call Scooter, your problem is not big. It should not cost too much. Call a few other place to...
