Notice that R functions can use both named parameters (as for header and sep) and positional parameters (AgeIncome.txt for the file parameter). The read.table function has a huge number of optional ...
The xlim and ylim functions specify explicit limits on the axes ranges. Without using xlim and ylim, R would guess at intelligent limit values. The mysterious looking xaxs="i" and yaxs="i" parameters ...
By using the regression function `svyglm()` in R, we can conduct a regression analysis that includes party differences in the same model as race. Using `svyglm()` from the survey package (rather than ...
10.3.1 Scatterplot matrix. Recall that we use SAS’s scatterplot matrix feature to quickly scan for pairs of explanatory variables that might be colinear. To do this in R we must first make sure we ...
Direct regression modeling of the effect of covariates on the cumulative incidence function (CIF) for competing risks data has been proposed, among others, by Fine and Gray, 6 and by Klein and ...
Learn what is Linear Regression Cost Function in Machine Learning and how it is used. Linear Regression Cost function in Machine Learning is "error" representation between actual value and model ...
Specialization: Statistical Modeling for Data Science Applications Instructor: Brian Zaharatos, Director, Professional Master’s Degree in Applied Mathematics Prior knowledge needed: Basic calculus ...
Nonlinear regression is a form of regression analysis in which data is fit to a model and then expressed as a mathematical function. Simple linear regression relates two variables (X and Y) with a ...
