Response to your post, from DHS Senior Sampling Specialist, Ruilin Ren: For Nigeria DHS 2008 (NDHS 2008), the stratification is defined by crossing HV023 with HV025 at household level. The Stata Journal is published quarterly by the Stata Press, College Station, Texas, USA. Basic syntax and usage. To compute confidence intervals, coefplot collects the variances of the coefficients from the diagonal of e(V) (or e(V_mi) for estimates from mi) and then, depending on whether degrees of freedom are available in scalar e(df_r) (or in matrix e(df_mi) for estimates from mi), applies the standard formulas for confidence intervals based on the t-distribution or the normal. The svyset command tells Stata everything it needs to know about the data set’s sampling weights, clustering, and stratification. If you need weights in a svy design, you should set them by the svyset command before using commands with svy prefix. All subsiquent analyses, in particular descriptive and bivariate statistics, must account for the survey design to produce unbiased mean and accurate variance estimates. Elkasabi is a Sampling Statistician at The DHS Program. Our Stata programs are the major source for information on our extracts. Stata does not have a special command for survival analysis with survey data, so we will use. census microdata and provides easy access to this data with enhanced documentation. Stata’s suite of commands for survey data analysis relies on properly identified survey design characteristics for point estimation, model fitting, and variance estimation. Stata can use cases with non-positive sampling weights by specifying iweight instead of pweight; hence the total number of cases read is the total number of cases used.
