Here, all outlier or missing values are substituted by the variables’ mean. A better alternative and more robust imputation method is the multiple imputation. In multiple imputation, missing values or outliers are replaced by M plausible estimates retrieved from a prediction model. The outlier becomes the dependent variable of a prediction One of the strengths of content validation is the simple and intuitive nature of its basic idea, which holds that what a test seeks to measure constitutes a content domain and the items on the test should sample from that domain in a way that makes the test items representative of the entire domain. Content validation methods seek to assess this quality of the items on a test. The variables are measured at an annual frequency and are winsorized at the 1% and 99% levels for each year. In some models, we also include the HKS ratio, the main variable of interest in Hong et al. (2008) , to control for the possible effect of individual investors on firm valuation and to provide a contrast between the effects of individual and institutional investors. In all model Statistical functions (scipy.stats)¶This module contains a large number of probability distributions, summary and frequency statistics, correlation functions and statistical tests, masked statistics, kernel density estimation, quasi-Monte Carlo functionality, and more. On discussion forums, I often see questions that ask how to Winsorize variables in SAS. For example, here are some typical questions from the SAS Support Community: I want an efficient way of replacing (upper) extreme values with (95th) percentile. I have a data set with around 600 variables and The independent variables We winsorize the resulting weight (w i,ac) by replacing the top 2% of observations, with the value at the 98th percentile used as the cut-off point. 9. Finally, we Examples abound in common language regarding predictive variables, yet confusion and fundamental misunderstandings surround the topic. Because of the frequent use and communication of predictor variables in behavioral and medical sciences, it is We winsorize all continuous variables in our study at the 2.5% and 97.5% levels, similar to Da et al. (2015). Music Sentiment ranges from −0.024% (Turkey) to 0.109% (Latvia). Weekly average stock market returns range from −0.009% (Turkey) to 0.449% (Taiwan), and weekly average stock market volatility ranges from 0.648% (Malaysia) to 2.060% (Argentina). The average autocorrelation for Music
