Simple and Multiple Linear Regression in Python explained with help of practical examples. First we start with simple linear regression analysis
Knowing the difference between parametric and nonparametric test will help you chose the best test for your research. A statistical test, in which specific assumptions are made about the population parameter is known as parametric test. A statistical test used in the case of non-metric independent variables, is called nonparametric test.
The number and type of possible statistical tests in experimental science can be bewildering. Luckily choosing the right test can be made alot easier by first considering the question: Is your data categorical or continuous? Categorical data is typically percentage … Continue reading →
