Strauss is a Digital Audio Workstation / Notation software that attemps to create a more efficient workflow for the modern composer.The ultimate goal is that note input is done through the notation side all the while there is an entire DAW underneath it that allows for fine tuning of notes and their sounds. Strauss is "basic feature" complete and is fully capable of producing music with.

QUESTION
I have a follow up question from my previous post.
Upon creating mppm models like these:
...ANSWER
Answered 2022-Jan-03 at 01:13First let me explain that, for Gibbs models, the likelihood is intractable, so anova.mppm
performs the adjusted composite likelihood ratio test, not the likelihood ratio test. However, you can essentially treat this as if it were the likelihood ratio test based on deviance differences.
- whether each individual id shows significant regularity
I am aware I could build separate ppm models for each id to test for significant regularity in each id, but I am not sure this is the best approach.
This is appropriate. Use ppm
to fit a Strauss model to an individual point pattern, and use anova.ppm
to test whether the Strauss interaction is statistically significant.
- whether some groups of ids show significantly stronger inhibition than other groups, for example, whether ids 1-7 are are significantly more regular than ids 8-10.
Introduce a new categorical variable (factor) f
, say, that separates the two groups that you want to compare. In your model, add the term f:str
to the interaction formula; this gives you the alternative hypothesis. The null and alternative models are identical except that the alternative includes the term f:str
in the interaction formula. Now apply anova.mppm
. Like all analyses of variance, this performs a two-sided test. For the one-sided test, inspect the sign of the coefficient of f:str
in the fitted alternative model. If it has the sign that you wanted, report it as significant at the same p-value. Otherwise, report it as non-significant.
- perform pairwise comparisons of regularity between different ids.
This is not yet supported (in theory or in software).
[Congratulations, you have reached the boundary of existing methodology!]
QUESTION
I just started getting into spatial analysis and am fitting some models to my data. My main goal is to test for spatial regularity (whether there is inhibition between points).
I created my hyperframe for the data below. There are 6 point patterns (Areas), 4 in subhabitat 1, and 2 in subhabitat 2.
...ANSWER
Answered 2021-Dec-27 at 08:20First, please learn how to make a minimal reproducible example. This will make it easier for people to help you solve the problem, without having to guess what was in your data.
In your example, the columns named Area
and Subhabitat
in the hyperframe H
are character vectors, but in your code, the call to mppm
would require that they are factors. I assume you converted them to factors in order to be able to fit the model fittest8
. (Another reason to make a working example)
You said that your example was similar to one on page 700 of the spatstat book which does work. In that case, a good strategy is to modify your example to make it as similar as possible to the example that works, because this will narrow down the possible cause.
A working example of the problem, similar to the one in the book, is:
QUESTION
I would like to fit a single model to several independent datasets in R
using the spatstat
package. Here, I have 3 independent datasets (ppp
objects called NMJ1
, NMJ2
, and NMJ3
), to which I want to fit a common model. The way to go should be to use the mppm
function:
ANSWER
Answered 2021-Nov-20 at 05:40This is not currently implemented in a neat way for mppm
, that is, for fitting models to several point pattern datasets. It is on the "to do" list.
(For fitting models to a single point pattern dataset, see the last paragraph below.)
Your code is OK, except for one problem: it assumes that it is valid to compare the log pseudolikelihood values of two models fitted with different values of r
. That's not always true because, by default, ppm
and mppm
use the border method of edge correction, and by default, the border distance rbord
is chosen to be equal to the interaction distance r
. In your code, rbord
is different for each model, so the pseudolikelihoods are not strictly comparable (effectively the models are based on different "sample sizes").
To avoid this problem, you can either explicitly set the border distance rbord
to be equal to the maximum value of r
that will be used:

Answered 2021-Nov-10 at 04:30Problem: you are writing to file in the end only once but processing more student data in the for loop before. The x variable only stores the final value and writes the student 002 data only.
QUESTION
I am working using the spatstat library in R.
I have several point pattern objects built from my own dataset
. The point patterns contain only the x and y coordinates of the points in them. I wanted to fit the point patterns to a Gibbs process with Strauss interaction to build a model and simulate similar point patterns. I was able to use ppm function for that purpose if I work with one point pattern at a time. I used rmhmodel function on the ppm object returned from the ppm
function. The rmhmodel
function gave me the parameters beta
, gamma
and r
, which I needed to use in rStrauss function further to simulate new point patterns. FYI, I am not using the simulate function directly as I want the new simulated point pattern to have flexible number of points that simulate does not give me.
Now, if I want to work with all the point patterns I have, I can build a hyperframe
of point patterns as described in the replicated point pattern chapter of the Baddeley
textbook, but it requires mppm function instead of ppm function to fit the model and mppm
is not working with rmhmodel
when I am trying to figure out the model parameters beta
, gamma
and r
.
How can I extract the fitted beta
, gamma
and r
from a mppm
object?
ANSWER
Answered 2020-Aug-27 at 07:32There are several ways to do this.
If you print
a fitted model (obtained from ppm
or from mppm
) simply by typing the name of the object, the printed output contains a description of the fitted model including the model parameters.
If you apply the function parameters
to a fitted model obtained from ppm
you will obtain a list of the parameter values with appropriate names.
QUESTION
Problem:
Let's say that table customers (id, name, email, .. )
is encoded using utf-8 (utf8_general_ci collation).
This table also has a unique key constraint on column email
.
When trying to change the collation to utf8mb4 using
ALTER TABLE customers CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
,
some entries cause the unique index constraint to flare up, because they are considered duplicates.
Example:
...ANSWER
Answered 2020-Jul-07 at 10:20In German, ß
is considered basically equal to ss
.
While the xxx_unicode_ci
collation respects that, the xxx_general_ci
does not, so you switched from a collation that considers "straus@email.com" not the same as "strauß@email.com" to one that does.
Actually, xxx_general_ci
treats ß
and s
the same, so it would complain about "straus@email.com" and "strauß@email.com" instead.
See the documentation:
_general_ci Versus _unicode_ci Collations
For any Unicode character set, operations performed using the xxx_general_ci collation are faster than those for the xxx_unicode_ci collation. For example, comparisons for the utf8_general_ci collation are faster, but slightly less correct, than comparisons for utf8_unicode_ci. The reason is that utf8_unicode_ci supports mappings such as expansions; that is, when one character compares as equal to combinations of other characters. For example, ß is equal to ss in German and some other languages. utf8_unicode_ci also supports contractions and ignorable characters. utf8_general_ci is a legacy collation that does not support expansions, contractions, or ignorable characters. It can make only one-to-one comparisons between characters.
QUESTION
I am currently building a food app using Yelp Fusion API. There are two models called Business and BusinessDatail in my project. To list up restaurants in a tableView, I fetch a restaurant list from backend and custom decode it as an array of Business, [Business]. And then, when a tableViewCell of Business is clicked, I fetch detailed business info and custom decode it as a BusinessDetail.
