Best Online Course For Statistics, with the introduction of Deep Learning and Neural Networks, statistics, number crunching, and data science are essential skills. For newcomers, working with large data sets and making significant inferences...
Regression analysis in statistics, Regression analysis is a technique for identifying patterns in data. You might think there’s a link between how much you eat and how much you weigh, for example; regression analysis...
Ad Hoc Analysis, A graph of data is sometimes the outcome of ad hoc analysis. Ad hoc means “just for a certain reason.” In business intelligence, ad hoc analysis is performed to answer a...
Similarity Measure Between Two Populations, The Brunner Munzel test (also known as the Generalized Wilcoxon Test) is a nonparametric statistical test for determining whether two samples are stochastically equal. Stochastic equality is a measure...
Rejection Region in Hypothesis Testing, What is the definition of a Rejection Region? A rejection region is a section of a graph where the null hypothesis is rejected (assuming your test results fall into...
An educated assumption about something in the world around you is a hypothesis. It should be able to be verified through experiment or observation. Consider a new drug that you believe may be effective....
Unequal Variance t-test in R, When the variances of two independent groups are not considered to be equal, Welch’s t-test is used to compare their means. We can use the t.test() function in R...
Test for Normal Distribution in R, Many statistical tests, such as correlation, regression, t-test, and analysis of variance (ANOVA), presuppose that the data has particular features. They demand that the data follow a normal...
SVM in Machine Learning, we’re going to talk about the R package e1071 today. We’ll learn how to use R to train and test SVM models, as well as the core functions of the...
glm function in r, we’ll look at what generalized linear models are in R and how to make them. We’ll also go over Logistic and Poisson Regression in depth. So, let’s get this tutorial...
