python无内置fit函数。返回如下出错信息：>>> fit(0.8)Traceback (most recent call last):File "<stdin>", line 1, in <module> NameError: name 'fit' is not defined
Option A: Install from pypi pip install linefitOption B: Clone this repo and run following to build:pip install git+https://github.com/Kin-Zhang/linefit python3 -c 'import linefit; print("linefit ground seg lib import success")'
Doing so may take little effort: a single line FREQUENCIES command in SPSS can create many histograms or bar charts in one go.Sadly, the situation for scatterplots is different: each of them requires a separate command. We therefore built a tool for creating one, many or all scatterplots ...
