looking for equations and formulas for confidence intervals, t stat, p value, anova, regression

basically just synthesized notes for doing stats off the computer.

+K obviously plus vid likes
 
Do you actually want to know how to do it, or are you just looking for the Business/Economics major explanation? If I'm going to explain it to you, you better be damn good with measure theory and topological representations of solution points. I damn well can't explain the Jordan canonical form without it.
 
1. what is the equation of the line which best approximates an assumed linear relationship between average selling price and size of home in the area

regression line......

residual standard error

percent of variation

F- test to determine if linear relationship exists

test statistic F=______

P- Value

Traditional hypothesis testing

Confidence interval
 
1, 2. How much of a background do you have running time series analysis in linear algebra? The best fit line through your data set is going to be something called the Least Squares Approximation of the the points on the data set. This approximation technique works for n-many dimensions for arbitrarily many data points at countably many times. Consequently, your RSE also depends on this.

3. Percent of variation: Simply your R^2 value, otherwise known as the coefficient of determination.

4. Self Explanatory

5. P-values: This is, given some random variable X with CDF and PDF , find P{X
 
Sounds like you're screwed. If you are having trouble with all of those topics there's no way you're going to pass the test. ANOVA is immeasurably more complicated than simple t-tests/intervals.
