I have set of value in float (always less than 0). Which I want to bin into histogram, i,e. each bar in histogram contain range of value [0,0.150) The data I have looks like this: 0.000 0.005 0.124 0.000 0.004 0.000 0.111 0.112 Whith my code below I expect to get result that looks like [0, 0.005) 5 [0.005, 0.011) 0 ...etc.. I trie...
Is there a way to specify bin sizes in MySQL? Right now, I am trying the following SQL query: select total, count(total) from faults GROUP BY total; The data that is being generated is good enough but there are just too many rows. What I need is a way to group the data into predefined bins. I can do this from a scripting language, but...
I am trying to perform a binning average. I am using the code: Avg = mean(reshape(a,300,144,27)); AvgF = squeeze(Avg); The last line gets rid of singleton dimensions. So as can be seen I am averaging over 300 points. It works fine except for times when I have a total number of points not equal to a multiple of 144*300. Is there any ...
What is a good way to bin numerical values into a certain range? For example, suppose I have a list of values and I want to bin them into N bins by their range. Right now, I do something like this: from scipy import * num_bins = 3 # number of bins to use values = # some array of integers... min_val = min(values) - 1 max_val = max(value...
I know how to create a histogram (just use "with boxes") in gnuplot if my .dat file already has properly binned data. Is there a way to take a list of numbers and have gnuplot provide a histogram based on ranges and bin sizes the user provides? ...
Background A PostgreSQL database uses PL/R to call R functions. An R call to calculate Spearman's correlation looks as follows: cor( rank(x), rank(y) ) Also in R, a naïve calculation of a fitted generalized additive model (GAM): data.frame( x, fitted( gam( y ~ s(x) ) ) ) Here x represents the years from 1900 to 2009 and y is the a...
If I have a set of data Y and a set of bins centered at X, I can use the HIST command to find how many of each Y are in each bin. N = hist(Y,X) What I would like to know is if there is a built in function that can tell me which bin each Y goes into, so [N,I] = histMod(Y,X) would mean that Y(I == 1) would return all the Y in bin 1...
