Data Management

Statistical Consulting Group covers every aspect of Data Management, e.g., CRF design, data entry, database design, data cleaning, outlier analysis, and data validation.

                Data Cleaning

We are dedicated to detecting and correcting corrupt or inaccurate records from a record set, table, or database. The process of data cleaning includes data auditing, workflow specification, workflow execution, post-processing, and controlling. We use popular methods. Those include parsing, data transformation, duplicate elimination, and statistical methods. By analyzing the data using the values of mean, standard deviation, range, and clustering algorithms, we can find values that are unexpected and thus erroneous.

                Measuring Outliers and Influential Points

We can examine any standardized residual greater than about 3 in absolute value, Hat element greater than 3p/n (p=k+1, k degrees of freedom), a Cook’s distance > 1, and Mahalanobis’s distance for case. We can run Outlier Analysis such as a run-sequence plot,  a scatter plot, a histogram, and a box plot.

Tests for Reliability, Validity, and Power

We can test reliability (such as Cronbach’s alpha, test-retest reliability, split-half reliability, and inter-rater reliability) and validity (such as content validity, construct validity, criterion validity, internal validity, and external validity).

Data Analysis

We can design and perform the required statistical analyses. We select the appropriate statistical methods to address your research questions. We are experts in statistical analysis such as t-test, ANOVA, traditional regression, logistic regression, MANCOVA, factor analysis, cluster analysis, survival analysis, time series analysis, canonical correlations, discriminant analysis, and more advanced statistical techniques such as structural equation modeling (SEM), hierarchical linear modeling (HLM), and path analysis. We are experts in statistical programming languages such as SAS, SPSS, HLM, Mplus, and Access.
