If we start with a variable x, and generate a variable x*, the process is:x* = (x-m)/sdWhere m is the mean of x, and sd is the standard deviation of x.爱吃鸭架子 生肖水 13 To illustrate the process of standardization, we will use the High School and Beyond dataset (hsb2)...
If you want to get cute you can generate the RENAMES macro variable directly from the HAVE dataset by using an ARRAY and various SAS functions. data _null_; if 0 then set have; array old col: ; call symputx('renames',' '); do i=1 to dim(old); call symputx('r...
Stata 14 includes a new default random-number generator (RNG) called the Mersenne Twister (Matsumoto and Nishimura 1998), a new function that generates random integers, the ability to generate random numbers from an interval, and several new functions that generate random variates from nonuniform ...
A binomial logistic regression is used to predict a dichotomous dependent variable based on one or more continuous or nominal independent variables. It is the most common type of logistic regression and is often simply referred to as logistic regression. In Stata they refer to binary outcomes when...
Assumption #4: There needs to be a linear relationship between (a) the dependent variable and each of your independent variables, and (b) the dependent variable and the independent variables collectively. You can check for linearity in Stata using scatterplots and partial regression plots. Assumpti...
Using PCA will generate a range of solutions with different numbers of factors, from simplified 1-factor solutions to higher levels of complexity. However, the fewer number of factors employed, the less variance will be accounted for in the solution. ...
