For the length of stay analysis, we used the natural logtransformation as the data were right skewed. Giardiasis rates per water distribution area were normalized using a logtransformation. However, because of the skewed distribution of health-care costs, we used a logtransformation of health-care costs. A logtransformation was applied on these proportional differences to normalize them. As above, variance within conditions was stabilized by adding 1 to each score before producing a logtransformation. Linear regression was used, but some data sets retained unequal variances after logtransformation, and were not regressed. To meet statistical normality assumptions, all salivary cortisol data were transformed using a natural logtransformation. Data were analysed using non-transformed data and also, where there was a clear relation between mean and standard deviation, using a natural logtransformation. Scales were subject to logtransformation to correct for a mild skew. Such data have traditionally been transformed using a logtransformation. Response latencies received a logtransformation in order to reduce skewness. To account for the non-normal cost distributions, cost data were imputed after logtransformation and back transformed to their original scale after imputation. In view of the skewed distribution of the raw expenditure data, a logtransformation of the data was used in the regression. Data were normalized by logtransformation and rare species were downweighted. A common solution for this situation is to use one of two types of variance stabilization techniques: logtransformation and rank transformation. A logtransformation was performed on the total score of internalizing problems during adulthood to reduce skewness for parametric tests. The cases with zero income were given an imputed value of 1.0 real, which made their logtransformation zero. These examples are from corpora and from sources on the web.
