Logistic Regression Analysisestimates the log odds of an event. If we analyze a pesticide, it either kills the bug or it does not. Thus we have a dependent variable that has two values 0 = bug survives, 1 = bug

The LINEST function in WPS Office is used to perform linear regression analysis, which helps you find the best fit line through a set of data points. The function returns an array of values that can be used to calculate the slope, y-intercept, correlation coefficient, and other useful statis...
When it comes to analyzing data, P-value is an essential concept that helps to determine the significance of the results obtained from regression or correlation analysis. However, calculating P-value manually can be a daunting task, with a high probability of errors. That's where spreads...
Regression Testing was done once the smoke results were good on any new build deployed in the test environments. Regression Results were analyzed to ensure that the entire functionality works fine with the new build deployed. Regression Runs also covered the new test cases that were added for the...
In this post, I provide step-by-step instructions for using Excel to conduct a two-sample variance test and interpreting the statistical results. I also include links to supplementary information I’ve written. Before proceeding, ensure that Excel’s Data Analysis ToolPak is installed for Excel....
Here are the best practices to improve ROI in automation testing: Start with High-Value Test Cases:Automate repetitive, stable, and high-impact tests such as regression, smoke, and data-driven tests to maximize early returns. Use the Right Tools and Frameworks:Choose tools that fit your tech ...
A great counterpart to regression analysisCorrelation analysis also nicely leads to regression analysis. By comparison, regression analysis tells you what Variable A might look like based on a particular value of Variable B.In other words, correlation tells you there is a relationship, but reg...
Quantitative data: Apply statistical methods such as regression analysis, t-tests, ANOVA, or chi-square tests to identify patterns, relationships, and differences. Qualitative data: Use methods such as content analysis, thematic analysis, or coding to interpret textual or visual data. Use software ...
End-to-End Testing Exploratory Testing Visual Regression Testing Monkey Testing Non-Functional Testing Context-Driven Testing Software Application Testing Process Software application testing is performed by following the process given below: Test Planning This is the initial phase that outlines the testing...
