### How do I convert an insheet to a Stata file?

In the command line type: set mem 5000k and press “enter.” In the command line type: insheet using “C:/senate1.txt” (you need both the quotation marks and the txt on the end). Save as a Stata file by clicking in the upper left corner on “file” and then “save as” and make sure you remove the “*” and have .dta as a file extension.

### How do I create a neighboring state variable in Stata 10?

*For STATA 10. *NOTE: The setup below is to generate 1 neighboring state variable. In this case the created variable is rtwpolneighave2. You can create 1 new *neighboring states variable and save the dataset. To create a second neighboring states variable simply substitute the variable you want to

### Why is between estimator not used in regression analysis?

The between estimator uses only between or cross-section variation in the data. Because only cross-section variation in the dta is used, the coefficients of any individual-invariant regressors, such as time dummies, cannot be identified. It is seldom used.

## Finite difference heat transfer analyses in Excel

Finite difference analyses (FDA’s) are generally performed to predict the values of physical properties at discrete points throughout a body. In the case of a stationary body where heat transfer is primary phenomena, the temperature could be determined throughout as a function of heating or cooling on the boundaries, and the physical ...

Q Even if the variogram does not show a need for random intercept, but in an unbalanced study every subject does start with a different level of response which needs to be accounted for.

## Differences Between Statistical Software ( SAS, SPSS, and …

The difference between Equation (10) of SAS and Equation (13) of SPSS output, is that, they have an opposite corresponding signs, that is because, SAS considers the probability p = Prob( Drug = 0 ) which is the probability of the test drug, as its default, while SPSS considers p = Prob( Drug = 1 ) which is the probability of the reference drug ...

## Regression and multiple comparisons

In the above we looked at some cases of non-independence of tests. This is a problem that is not particular just to multiple comparisons, but to any statistical test. Suppose we did a regression analysis on a large dataset and then decided to examine a subset of it with a second regression.

Nov 20, 2009 · I created my own variable measuring the change in DLCO as a difference, and then did a one sample t test that the mean of that new variable (which would then be the mean difference) was zero. These two ways are actually the exact same method. In the first method, Stata creates the variable measuring the difference all on its own hidden from you.

## Summary - Lippincott Williams &amp; Wilkins

This eAppendix provides further details on two topics for which space limitations precluded in-depth discussion in the main text. First, regression discontinuity designs identify a local causal effect: the causal effect for the population close to the threshold; we discuss the generalizability of this estimand vis-à-vis the average causal effect identified in a randomized trial.
