Introduction

It only contains one function which accept a dataframe with missing values and replace the NaNs with mean value of the value around these NaNs. The imputation is linear, e.g. [nan,nan,5,8] => [-1,2,5,8], [3,nan,nan,9] => [3,5,7,9], [1,5,nan,nan] => [1,5,9,13]

Currently only DataFrame is accepted, I may consider to support any arrry-like object in the future.

Tips

1. This is actually a package for practice packaging in python. So there may be problems with the algorithm and the algorithm may not be efficient.
2. There should be at least 2 non-nan value in the input, otherwise the original DataFrame will be returned.
3. Only float point number is tested, so be careful if use this function with other value types
