In this talk I will discuss inference for high dimensional quantile regression, and present two new tests based on maximum-type statistics to detect the presence of significant predictors associated with the quantiles of a scalar response. The fi...
It first filters out any noise or outliers that may be present in the data. This is done through a series of algorithms that analyze the data based on statistical methods. For example, if a wind speed value is significantly different from the surrounding values and exceeds a certain threshold...
How to detect outliers in data envelopment analysis by Kourosh and Arash method One of the concerns about using non-parametric estimators such as Data Envelopment Analysis (DEA), is the presence of outliers. There are a good number of ... D Khezrimotlagh - IEEE 被引量: 2发表: 2015年 HSE...
