SQL Table-Valued Function to Find the Best Trend Line Using Linear Regression

Linear regression is probably one of the first regression techniques we run across. It is useful for explaining (and perhaps forecasting) data that has a linear nature, but where the underlying process is unknown.  Linear regression line between New Patient Data and  Marketing Expenses   This solution focuses on the practical aspects of finding the best trend line for a financial time series using SQL function. If you have a large dataset with multiple sets of x and y data points associated with some attribute, you can do a linear regression on each set with one query using GroupID. The great strength of the linear regression line is that it can clarify sometimes ambiguous line charts and quantify the results via the slope of the line.

Building a ML classifier on dentistry payment plans data using C#

I prefer the Naive Bayes approach, because while having small set of data, it seems to make better decisions than I did in many cases. Also, the other type of classifier seems to do better on clear-cut cases, but doesn't seem to handle uncertainty so well. In addition,   the naive Bayes classifier corresponds to a linear classifier in a particular feature space.                                                   Main Program Text Pre-processing Class   Naive Bayes Class


This blog presents a novel non-invasive approach for early diagnosis of prostate cancer from dynamic contrast enhanced magnetic resonance imaging (DCE-MRI).  In order to precisely analyze the complex 3D DCE-MRI of the prostate, a novel processing frame work that consists of four main steps is proposed. The first step is to isolate the prostate from the surrounding anatomical structures based on a Maximum a Posteriori (MAP) estimate of a log likelihood function that accounts for the shape priori, the spatial interaction, and the current appearance of the prostate tissues and its background (surrounding anatomical structures). In the second step, a non-rigid registration algorithm is employed to account for any local deformation that could occur in the prostate during the scanning process due to the patient’s breathing and local motion.  In the third step, the perfusion curves that show propagation of the contrast agent into the tissue are obtained from the se

What is Mean to Know The Patient Life Time Of Your Dental Patients?

How to Measure Patient Lifetime Value The Patient Lifetime Value is the  key success factor in operating any dental practice and it shows the ability to retain patients once they come in the door. By focusing on this long-term value, the  dental practice  can enjoy higher returns from his existing client base. What Is  Dental Patient  Life Time Value? PLT value is a prediction of the total worth of a d ental patient to  a  dentistry  over the entirety of their relationship. Most often, a dentist starts looking for advertising when he or she notices an acute need for patients, hoping for a short-term influx of new work. If the advertising is successful in bringing in patients, it is often terminated – at least until the next time the practice is not attracting enough new patients. Similarly, new patients are deemed monetarily unrewarding if their service includes only standard cleaning and examination procedures. This lack of long-term focus is perpetuated by
