Multiple Imputation of Missing Data Using Stata

imputation model should always include all the variables in the analysis model, including the dependent variable of the analytic model as well as any other variables that may provide information about the probability of missigness, or about the true value of the missing data. Theory should guide the decision as to which variables to include.

extensions are *.txt for tab-separated data and *.prn for space-separated data. Any statistical package can read these formats. •Record form (or fixed). Data is structured by fixed blocks (for example, var1 in columns 1 to 5, var2 in column 6 to 8, etc). You will need a codebook and to write a program (either in Stata, SPSS or SAS) to read ...

CHAPTER 7: CROSS-SECTIONAL DATA ANALYSIS AND REGRESSION 1. Introduction In all our statistical work to date, we have been dealing with analyses of time-ordered data, or time series: the same variable or variables observed and measured at consecutive points of time. Usually but not necessarily, the points of time are equally spaced.
