### 말뭉치

- In statistics, Kernel regression is a non-parametric technique to estimate the conditional expectation of a random variable.
^{[1]} - the function npreg of the np package can perform kernel regression.
^{[1]} - This leads to the technique known as kernel regression.
^{[2]} - This gives us a mathematical justification for using kernel regression in cases where it is possible to do so.
^{[2]} - On the down side, since we need to calculate the Gram matrix, kernel regression does not scale well – for large datasets turning to neural networks is a better idea.
^{[2]} - Bandwidth in kernel regression is called the smoothing parameter because it controls variance and bias in the output.
^{[3]} - In this example, a kernel regression model is developed to predict river flow from catchment area.
^{[3]} - In this example, a bandwidth value of 10 is used to explain kernel regression.
^{[3]} - The fundamental calculation behind kernel regression is to estimate weighted sum of all observed y values for a given predictor value, xi.
^{[3]} - Let’s see an application of multivariate kernel regression for the wine.csv dataset.
^{[4]} - Using only the blue data points, Gaussian Kernel Regression arrives at the approximated function given by the red line.
^{[5]} - The above equation is the formula for what is more broadly known as Kernel Regression.
^{[5]} - In robust nonparametric kernel regression context, we prescribe method to select trimming parameter and bandwidth.
^{[6]} - Kernel regression is an estimation technique to fit your data.
^{[7]} - The idea of kernel regression is putting a set of identical weighted function called Kernel local to each observational data point.
^{[7]} - In Kernel regression, what you do is to put a kernel (a kind of bump function) to each point of your X data.
^{[7]} - A SAS programmer recently asked me how to compute a kernel regression in SAS.
^{[8]} - "What is loess regression" and "Loess regression in SAS/IML" and was trying to implement a kernel regression in SAS/IML as part of a larger analysis.
^{[8]} - This article explains how to create a basic kernel regression analysis in SAS.
^{[8]} - A kernel regression smoother is useful when smoothing data that do not appear to have a simple parametric relationship.
^{[8]} - Kernel regression is a modeling tool which belongs to the family of smoothing methods.
^{[9]} - Unlike linear regression which is both used to explain phenomena and for prediction (understanding a phenomenon to be able to predict it afterwards), Kernel regression is mostly used for prediction.
^{[9]} - In this paper, we first review the latest developments of sparse metric learning and kernel regression.
^{[10]} - Then a novel kernel regression method involving sparse metric learning, which is called kernel regression with sparse metric learning (KR_SML), is proposed.
^{[10]} - The sparse kernel regression model is established by enforcing a mixed (2,1)-norm regularization over the metric matrix.
^{[10]} - Our work is the first to combine kernel regression with sparse metric learning.
^{[10]} - I am using kernel regression for build a relationship between independent and dependent variables in development period data.
^{[11]} - Train a default Gaussian kernel regression model with the standardized predictors.
^{[12]} - Below you will find a range of commented examples intended to help you become familiar with applied nonparametric kernel regression in R/RStudio using the np package.
^{[13]} - As in kernel density estimation, kernel regression involves choosing the kernel function and the bandwidth parameter.
