Using Python for data analysis--numpy basics: Arrays and Vector computing Ndarry, a multidimensional array with vector operations and complex broadcast capabilities for fast space-saving Standard mathematical function for fast operation of whole set of data without For-loop Tools for reading an

The Pandas object has some common mathematical and statistical methods. For example, the sum () method, which makes the column subtotal: the sum () method passed in Axis=1 is specified as a horizontal summary, which is subtotal: Idxmax () gets the index of the maximum value: There is also a rollup that is cumulative, cumsum (), compared to it and Su The difference between M ():The unique () method is used to return only values in the data: the Value_

Fourth NumPy basics: arrays and vector calculations To be honest, the main purpose of using NumPy is to apply vectorization operations. NumPy does not have much advanced data analysis capabilities, and understanding numpy and array-oriented computations can help to understand the pandas behind it. According to the textbook, the author's concern is mainly focused

Next article: using R and biocondufor gene chip data analysis (3): computing Median Normalization is translated from normalization. The purpose of normalization is to make measurements under various/group measurements or under various experimental conditions can be compared with each other to eliminate non-experimental differences between measurements.

array corresponds to a one-dimensional array, the slice of a two-dimensional array is a fragment of one-dimensional array: multidimensional Arrays index of multidimensional arraysIn a one-dimensional array, a single index value returns the corresponding scalar, and in a two-dimensional array, a single index value returns the corresponding one-dimensional array; In a multidimensional array, a single index value returns an array of a lower latitude, for example: Boolean index A Boolean index
