Brier score is an evaluation metric that is used to check the goodness of a predicted probability score. This is very similar to the mean squared error, but only applied for prediction probability scores, whose values range between 0 and 1. Overview In this tutorial, you will understand: What is Brier score? How is Brier …

One sample T-Test tests if the given sample of observations could have been generated from a population with a specified mean. If it is found from the test that the means are statistically different, we infer that the sample is unlikely to have come from the population. For example: If you want to test a …

Standard error of the mean measures how spread out the means of the sample can be from the actual population mean. Standard error allows you to build a relationship between a sample statistic (computed from a smaller sample of the population) and the population’s actual parameter. Standard Error – A practical guide with examples. Photo …

Confidence interval is a measure to quantify the uncertainty in an estimated statistic (like the mean) when the true population parameter is unknown. Training Custom Text Classification Model in spaCy. Photo by Jessica Wong. You will know 1. What is Confidence Interval? 2. Two types of Confidence Intervals problems 3. Difference between Population parameter vs …
T Test (Students T Test) is a statistical significance test that is used to compare the means of two groups and determine if the difference in means is statistically significant. In this one, you’ll understand when to use the T-Test, the different types of T-Test, math behind it, how to determine which test to choose …

P Value is a probability score that is used in statistical tests to establish the statistical significance of an observed effect. Though p-values are commonly used, the definition and meaning is often not very clear even to experienced Statisticians and Data Scientists. In this post I will attempt to explain the intuition behind p-value as …
