[Gretl-users] Re: First time user of Hansl and creating a matrix of Spearmans correlation

Hi Alison, there are some errors with the syntax: 1. Comments are done via the "#" symbol 2. In Hansl (Gretl's scripting language) lines do not end by ";" symbol Here is your script which runs fine here: <hansl> # Function to calculate Spearman correlations and p-values for a list of variables function matrix spearman_matrix(list variables) matrix SC = {} strings rnames = array(0) n = nelem(variables) loop i = 1..n loop j = 1..i-1 # Calculate Spearman correlation and p-value SC |= npcorr(variables[j], variables[i], spearman) # Construct row names rnames += sprintf("%s_%s", varname(variables[j]), varname(variables[i])) endloop endloop # Set column names cnameset(SC, defarray("Spearman", "t-stat", "p-value")) # Set row names rnameset(SC, rnames) return SC end function # Open your dataset # open panel2.gdt open mroz87.gdt # Specify the variables of interest #list variables = deflist("ROE", "ENV", "SOC", "GOV") list variables = WHRS KL6 WA WE # Calculate Spearman correlations and p-values matrix SC_matrix = spearman_matrix(variables) # Print the resulting matrix print SC_matrix </hansl> Artur Am 30.01.24 um 14:14 schrieb Alison Loddick: > Hi All, > > I have never used Hansl or Gauss before and I am trying to work out how > to get a programme working to create a matrix of spearman correlations. > Allin created one last month, which I tried to run and kept getting ‘No > redo information available’.
