Quantile regression is a type of regression analysis used in statistics and econometrics that estimates the relationship between the independent variables and specific quantiles (percentiles) of the dependent variable. Unlike ordinary least squares (OLS) regression, which estimates the mean of the dependen...
In the case of this library, a data profile is a dictionary containing statistics and predictions about the underlying dataset. There are "global statistics" orglobal_stats, which contain dataset level data and there are "column/row level statistics" ordata_stats(each column is a new key-value...
The normal distribution is a bell-shaped curve where data clusters symmetrically around the mean, useful in statistics and natural phenomena modeling.
If 1−α1−α is your confidence level, you can always find two quantiles q1−α/2+cq1−α/2+c, qα/2−cqα/2−c that will give you a working interval. There are a bunch though, and they all have different lengths. You want the shortest. If your density f(⋅)f(...
to the left is to say that it is negatively skewed. In this situation, the mean and the median are both less than the mode. As a general rule, most of the time for data skewed to the left, the mean will be less than the median. In summary, for a data set skewed to the left:...
