Step-by-step Example of Running a Regression: we learn to do regression using R statistics software. I'll walk through the code for running a multivariate regression - plus we'll run a number of slightly more complicated examples to ensure it's all clear.
Outline:
• We will walk through the R-Software Code to run a multivariate regression.
• Talk about the lm() Function in R
• We'll discuss complicating our regression model a bit
--o Add an Interaction Effect
--o Add a quadratic variable to a regression.

Predict who survives the Titanic disaster using Excel.
Logistic regression allows us to predict a categorical outcome using categorical and numeric data. For example, we might want to decide which college alumni will agree to make a donation based on their age, gender, graduation date, and prior history of donating. Or we might want to predict whether or not a loan will default based on credit score, purpose of the loan, geographic location, marital status, and income. Logistic regression will allow us to use the information we have to predict the likelihood of the event we're interested in. Linear Regression helps us answer the question, "What value should we expect?" while logistic regression tells us "How likely is it?"
Given a set of inputs, a logistic regression equation will return a value between 0 and 1, representing the probability that the event will occur. Based on that probability, we might then choose to either take or not take a particular action. For example, we might decide that if the likelihood that an alumni will donate is below 5%, then we're not going to ask them for a donation. Or if the probability of default on a loan is above 20%, then we might refuse to issue a loan or offer it at a higher interest rate.
How we choose the cutoff depends on a cost-benefit analysis. For example, even if there is only a 10% chance of an alumni donating, but the call only takes two minutes and the average donation is 100 dollars, it is probably worthwhile to call.

In this tutorial on Python for Data Science, You will learn about Multiple linear regression Model using Scikit learn and pandas in Python. You will learn about how to check missing data and Correlation.
This is the 30th Video of Python for Data Science Course! In This series I will explain to you Python and Data Science all the time! It is a deep rooted fact, Python is the best programming language for data analysis because of its libraries for manipulating, storing, and gaining understanding from data. Watch this video to learn about the language that make Python the data science powerhouse. Jupyter Notebooks have become very popular in the last few years, and for good reason. They allow you to create and share documents that contain live code, equations, visualizations and markdown text. This can all be run from directly in the browser. It is an essential tool to learn if you are getting started in Data Science, but will also have tons of benefits outside of that field. Harvard Business Review named data scientist "the sexiest job of the 21st century." Python pandas is a commonly-used tool in the industry to easily and professionally clean, analyze, and visualize data of varying sizes and types. We'll learn how to use pandas, Scipy, Sci-kit learn and matplotlib tools to extract meaningful insights and recommendations from real-world datasets.

1. Formula for slope is derived from the expression minSUM(y observed value -- y Predicted value)^2 using differential calculus. See text page 667.
2. Calculate Slope and Y-Intercept for Regression Line long hand.
3. Calculate Slope using the SLOPE Function
4. Calculate the y-Intercept using the INTERCEPT Function
5. Slope = Rise Over Run = For every one unit of x, how far does y move?
6. Y-intercept = y value where x = zero. = point at which line crosses axis
7. Use slope and y-intercept to create estimated simple linear regression equation (line or model)
8. From sample data, the slope and y-intercept are point estimates for the population parameters for slope and y-intercept
9. Use estimated simple linear regression line to make predictions
10. Be careful when making predictions with the estimated simple linear regression equation (line or model) when the x values are outside the range of the sample data. Why? Because the data may show a linear relationship over the range of sample data, but may show some other relationship outside that sampled range.
11. See how to use FORECAST function to make predictions.

From an existing multiple regression output produced with Excel 2007, I show you how to make point predictions and approximate 95% prediction intervals. The basic package of Excel does not have a routine for making predictions intervals, so I suggest a method of inflating the residual standard deviation statistic by 10% to get an approximate standard error of prediction.

5. Scatter Diagram with proper x and y axis labels to see if there is a relationship between two variables.
6. Direct, Positive Relationship: As x increases, y increases
7. Indirect, Negative Relationship: As x increases, y decreases

OpenMx runs on Mac OS X, Windows (XP, Vista, 7, 8), and several varieties of Linux. This means the same scripts you write in Windows will run in Mac OS X or Linux.
OpenMx is free and open source software for use with R that allows estimation of a wide variety of advanced multivariate statistical models. OpenMx consists of a library of functions and optimizers that allow you to quickly and flexibly define an SEM model and estimate parameters given observed data.
OpenMx can be used by those who think in terms of path models or by those who prefer to specify models in terms of matrix algebra. OpenMx is extremely powerful, taking full advantage of the R programming environment. This means that complicated models and data sets can be specified and modified using the R language.
