Variable Coef Std Err t-stat p-value CI 2.5% CI 97.5% eye(m,n) Creates an m n matrix with ones on the main diagonal and ze-ros elsewhere (the main diagonal consists of the elements with equal row and column numbers). Вот краткий пример того, как это сделать с помощью pandas.ols: import matplotlib.pyplot as plt CME 102 Matlab Workbook 2008-2009 3/55 1 Matlab Basics 1.1 Matrix and Vector Creation Commands: Placed after a command line to suppress the output. How do I, in the simplest way possible, estimate this trend and add the predicted values as a column to my data frame? I suppose I could recalculate a running-quarter variable, but there most be a more comfortable way of doing this?

First of all, these answers might be not up to date: pandas improved, and now itself includes an OLS component.
I've found some answers here, but they all include statsmodels. Also, I would like to compute this trend only conditional on data before, say, 2006.
I would like to add, in the most simple way, a linear trend (with intercept) onto this graph.
I have time-series data, as followed: emplvl
