# Quantile Regression in Machine Learning

## What is Quantile Regression?

Quantile regression is a way of statistical analysis that compares historical data points (data set size, number of data points, kind of data, etc.) to the expected outcome. The output from the analysis is what we want to measure and this can be used for all kinds of data analysis purposes: forecasting, competition analysis, etc. Basically, Quantile regression is used to study relationships between various quantities such as time-varying variables, kind of inputs, output from the model, and so on.

## What is the use of Quantile Regression?

Why would we want to study relationships between so many variables? Basically, the more the number of dimensions, the more the analysis will be long term. Also, if the number of dimensions is small, the statistical test may take too long to detect any significant result. So, it is important to select a statistical test that is sensitive to the number of dimensions that are analyzed.

In general terms, regressing data points means to take the mean of the data points obtained from the original data set. For example, say that we have a data set that was originally set up with three categories (rows, columns, and so on) and now we want to regress the data points to the mean squared value of each category. We can do this by simply dividing the data set into two parts. One part is the original data set, and the other part is the new mean square value of each category. This can be done by dividing each category into smaller subgroups and then assigning weights to these subgroups to effectively map the regression lines to their Mean Square values.

## Role of Quantile Regression:

In machine learning the main concept is that when a machine can successfully classify a large amount of data, the classification accuracy will be very high. Of course, not all of the data will be high, but if the machine can successfully class even 50% of the data, you will see a big increase in the accuracy of your classification results. However, accuracy does not only come from how high the classifier can predict the mean or squared value of a variable, it also comes from how accurately the classifier can predict the actual value of the variable given the data it is trained on. This is where what is Quantile regression in machine learning comes in.

Basically, Quantile regression deals with how well a machine can predict what the data points would be after it has been fed into the computer program for classification. Basically, this is done by plotting the data points against the predicted square value of each category given the data that has been fed into the machine. What makes this method very accurate is the fact that you can plot the data points either before or after the data is actually fed to the machine. This way you can actually plot the data points along the x-axis before the actual data sets are collected, and they can be plotted on the y-axis afterwards. This makes for a much more accurate image of what the data points would look like as they are actually recorded in the computer system.

## Conclusion:

Quantile regression in machine learning is what makes the accuracy of the predictions high. The accuracy of the predicted data points is what allows the classification result to be a valid estimate as well as the high precision. In machine learning, quantile regression causes the most accurate estimates and the high precision. Traditional statistical classification methods, which many high school students learned how to perform when learning statistics in high school, do a poor job of classifying the data because they don’t take into account the standard deviation of the distribution. This results in very low precision and an invalid estimate of what the mean and standard deviation of the distribution will actually be.
