SETP stepwise regression, you can remove the meaningless variable backwards, you can add a new variable to the forward regression
Lm (y~x1, subset=1:100) selects only the first 100 data for regression
Lm (Y~i (X1+X2)) to (X1+X2) regression
Lm (Y~ploy (x,3,raw=true)) Y is the three-quadratic polynomial regression of x
Lm (log (y) ~ x1

When you print the log with ProgressBar, why not add color to them! In fact, when there is a big mistake, it can give you a quick reminder.
Colorama is easy to use. Just write it in your script and add it to the text you want to print:

Today's challenge is the density map:The appearance of the myriad, we always need a graph can be a glance to show the characteristics of the data. Data distribution maps are undoubtedly very reflective of data characteristics (user symptoms). It works better with median and 9-bit.For example, because of the secrecy, I hide what each line represents, and what the data output is. From the lines alone, you can see how many people in each channel are accustomed to buying things before, and presumabl
