MANOVA stands for Multivariate ANalysis Of VAriance is an extension of ANOVA. In ANOVA we have only one dependent variable but in MANOVA we have more than one dependent variable to include. It is used to test the differences between multiple factors of independent variables. MANOVA allows us to check the difference between different factors […]
ANOVA, or ANalysis Of VAriance, is a statistical practice for confronting means over groups. It is an abstraction of t-test which is used for comparing the means of two groups. When we are coping with groups more than two we move ahead to ANOVA. It assesses whether there are any statistically significant differences in the
In R Programming, logistic regression is a grouping approach used to determine the likelihood of happening success and failure. When the dependent variable is binary (0/1, True/False, Yes/No), logistic regression is implemented. In a binomial distribution, the logit function is leveraged as a link function. The logistic function, frequently known as the sigmoid function, is
What are outliers? Outliers are data points in a dataset that are different from the rest of the data. They can have immensely high or low values and can skew statistical analysis and models. Outliers can rise for various causes, including measurement errors, inaccurate data entry, or true abnormal events in the data. Finding and
Normality refers to the typical feature of a normal distribution, which is a precise type of probability distribution with uncommon qualities that make it particularly relevant for various statistical investigations. In many statistical analysis, determining whether your data follows a normal distribution requires checking the normality of data. There are different ways to check for
