Nonlinear regression with python – what’s a simple method to fit this data better?

This example code uses an equation that has two shape parameters, a and b, and an offset term (that does not affect curvature). The equation is “y = 1.0 / (1.0 + exp(-a(x-b))) + Offset” with parameter values a = 2.1540318329369712E-01, b = -6.6744890642157646E+00, and Offset = -3.5241299859669645E-01 which gives an R-squared of 0.988 and … Read more

Python 3: Multiply a vector by a matrix without NumPy

The Numpythonic approach: (using numpy.dot in order to get the dot product of two matrices) The Pythonic approach: The length of your second for loop is len(v) and you attempt to indexing v based on that so you got index Error . As a more pythonic way you can use zip function to get the columns of a list then use starmap and mul within a list comprehension:

Moving Average Pandas

The rolling mean returns a Series you only have to add it as a new column of your DataFrame (MA) as described below. For information, the rolling_mean function has been deprecated in pandas newer versions. I have used the new method in my example, see below a quote from the pandas documentation. Warning Prior to version 0.18.0, pd.rolling_*, pd.expanding_*, and pd.ewm* were module level functions and are … Read more
