Examples of regression data and analysisThe Excel files whose links are given below provide examples of linear and logistic regression analysis illustrated with RegressIt. Most of them include detailed notes that explain the analysis and are useful for teaching purposes. Links for examples of analysis...
Regression Analysis: Identify trends in pollution and its correlation with health outcomes. Dataset Link:Air Quality Measures Tips Data Cleaning:Clean and transform the dataset. You can use Excel’s Text to Columns, Find and Replace, and Remove Duplicates features. ...
After entering the formula in F2:H6 ofFigure 6.2, I copied and saved it as the resultvaluesin F8:H12. That is because I want you to be able to use Excel’s Solver, or to change the regression coefficients manually, so you can compare the results of that change with the original resu...
We begin with the case of one independent variable, i.e. a logistic regression model of form y =β1x+β0. In particular, we assume this variable is normally distributed. We can estimate the minimum sample size when comparing the null hypothesis H0:β1= 0 with the alterna...
Another reason for designating the sample group with the larger mean as the first sample is to obtain the correct result from the Excel data analysis toolt-Test: Two-Sample Assuming Equal Variances. The test statistic (T Stat in the Excel output) and the Critical t value (t Critical two-...
