This is similar to my previous questions posted: Create new column with distinct character values But I also wanted some additional information. df: ID <- c(1,1,1,1,1,1,1,2,2,2,2,2) color <- c("red","red","red","blue","green","green","blue", "yellow","yellow","red","blue","green") df <- data.frame(ID,color) ID color 1 1 red 2 1 red 3 1 red 4 1 blue 5 1 green 6 1 green 7 1… Read More Create new column with frequency of values
I have frequency counts based on three variables y , Col1, Col2 as shown below Col1 Col2 y n Good Poor 0 0 Good Poor 1 0 Good Rich 1 13 Good Rich 0 8 Bad Poor 0 8 Bad Poor 1 0 Bad Rich 1 15 Bad Rich 0 5 How do I expand… Read More r create observations from frequency counts
I need to calculate frequency of float elements in list. Convert them to int I can’t, because I need to manipulate then float values, not int. My try in the code below: values = [21.963, 23.4131, 23.7639, 24.3934, 24.5237, 25.2829, 25.394] df = pd.Series(values).value_counts().sort_index().reset_index().reset_index(drop=True) df.columns = [‘Element’, ‘Frequency’] frequency = (df[‘Frequency’].values).tolist() hovewer I want to… Read More Calculate frequency of float values in list Python
I want to have the final result based on the frequency. As shown in the figure, in the red area, V1 shows up more, so of course the final result is "V1". It works with the formula: =INDEX(A2:A11,MODE(MATCH(A2:A11,A2:A11,0))) But for the blue area, the frequency of V1 and V2 is the same, but I still… Read More How to have the result of both values when they have the same frequency in Excel?
Writing a function to calculate date based on relativedelta. How do I make the ‘frequency’ a variable? e,g, relativedelta(years=5), ability to define frequency: "years", "months", "days" etc.. Tried f-string literal but i think the apostrophe is giving issues. def date_ago(date, period, frequency): """date: "yyyy-mm-dd" frequency: "years", "months", "weeks", "days" period: interger """ date_ago = datetime.strptime(date,… Read More Variables within a function
The following data exists in the database: [ { "_id": { "$oid": "628c787de53612aad30021ab" }, "ticker": "EURUSD", "dtyyyymmdd": "20030505", "time": "030000", "open": "1.12161", "high": "1.12209", "low": "1.12161", "close": "1.12209", "vol": "561", "id": 1 }, { "_id": { "$oid": "628c787de53612aad30021ac" }, "ticker": "EURUSD", "dtyyyymmdd": "20030505", "time": "030100", "open": "1.12206", "high": "1.1225", "low": "1.12206", "close": "1.1225", "vol": "1223",… Read More Unable to retrieve multiple values from database
I am creating a sparse neural network as described in the image below. Keras only provides a dense layer and we can’t choose how many neurons we want to be connected to the previous layer. For implementing this using Keras, I am trying to implement the following approach: 1- Get the Gradient Matrix of each… Read More How can I Get, Edit and Set Gradient Matrix in Training of Keras Model?
Problem Statement: Some near infrared spectra on 60 samples of gasoline and corresponding octane numbers can be found by data(gasoline, package="pls"). Compute the mean value for each frequency and predict the response for the best model using the five different methods from Question 4. Note: This is Exercise 11.5 in Linear Models with R, 2nd… Read More How do I use the means of the columns of a matrix as prediction values in a linear regression in R?
This code appends a new value directly to a tuple. But tuples are supposed to be nonchangeable. Could someone explain what is happening here? word_frequency = [(‘hello’, 1), (‘my’, 1), (‘name’, 2), (‘is’, 1), (‘what’, 1), (‘?’, 1)] def frequency_to_words(word_frequency): frequency2words = {} for word, frequency in word_frequency: if frequency in frequency2words: frequency2words[frequency].append(word) else: frequency2words[frequency]… Read More How to append a more values to a tuple
I want to create a function in R which summarize a vector of numbers into a dataframe representing a frequency table with k classes. The Input are: x : a vector of numeric data of any length k : an integer greater than 1 that represents the number of equal width classes dividing the support… Read More Create a function in R having these input and outputs
