[R] Shaded area

2023-03-01 Thread George Brida
Dear R users,

I have an xlsx file (attached to this mail) that shows the values of a
"der" series observed on a daily basis from January 1, 2017 to January 25,
2017. This series is strictly positive during two periods: from January 8,
2017 to January 11, 2017 and from January 16, 2017 to January 20, 2017. I
would like to plot the series with two shaded areas corresponding to the
positivity of the series. Specifically, I would like to draw 4 vertical
lines intersecting the x-axis in the 4 dates mentioned above and shade the
two areas of positivity. Thanks for your help.

[R] Logistic regression for large data

2022-11-11 Thread George Brida
Dear R users,

I have a database  called Base.csv   (attached to this email) which
contains 13 columns and 8257 rows and whose the first 8 columns are dummy
variables which take 1 or 0. The problem is when I wrote the following
instructions to do a logistic regression , R runs for hours and hours
without giving an output:

Base=read.csv("C:\\Users\\HP\\Desktop\\New\\Base.csv",header=FALSE,sep=";")
fit_1=glm(Base[,2]~Base[,1]+Base[,10]+Base[,11]+Base[,12]+Base[,13],family=binomial(link="logit"))

Apparently, there is not enough memory to have the requested output. Is
there any other function for logistic regression that handle large data and
return output in reasonable time.

Many thanks

Kind regards

George

[R] Mapping of groups of countries

2021-12-29 Thread george brida
Dear R users,

I would like to map with R the following countries (with their names on the
map) as follows: the first group in red composed by China, Bangladesh,
Eypt, Indonesia, South Korea, Nigeria. The second group in blue composed by
Brazil, Pakistan, Philippines, Vietnam.

The third group in green solely composed by South Africa.

Finally, the fourth group in orange composed by India, Mexico and Turkey.

I'd also like a legend that assigns the different colors to the various
group.
I tried several times with library maps but it seems that I failed to find
the real setting of xlim and ylim. Can you please help me, I will be very
grateful.

Best regards
George

Re: [R] Matrix multiplications

2016-05-21 Thread george brida
Roy,

Yes, t(y-X %*% b) is the transpose of y-X %*% b. In principle the product
of  t(y-X %*% b) *(y-X %*% b) is a scalar, I don't know why I have an error
message after the following line:

(t(y-X %*% b)%*%(y-X %*% b)/(length(y)-ncol(X)))*solve(t(X)%*% X)

Thanks

[R] Matrix multiplications

2016-05-21 Thread george brida
Dear R users:

I have written the following lines :

>x=c(10,11,12,13,14,17,15,16,10,11,41,25,26,14,12,14,15,20,14,22)
> x=matrix(x,ncol=2)
> a=matrix(1,nrow(x),1)
> X=cbind(a,x)
>y=c(12.00, 11.00, 13.00, 12.50, 14.00, 18.50, 15.00, 12.50, 13.75, 15.00)

>b=solve(t(X)%*% X)%*% t(X)%*% y

when I wrote the following line
>(t(y-X %*% b)%*%(y-X %*% b)/(length(y)-ncol(X)))*solve(t(X)%*% X)
I have obtained an error message, I don't know why namely (t(y-X %*%
b)%*%(y-X %*% b)/(length(y)-ncol(X))) is a scalar:
> (t(y-X %*% b)%*%(y-X %*% b)/(length(y)-ncol(X)))
 [,1]
[1,] 3.620354


Can you please help me.

Thank you

George

[R] Problem with plm package

2014-01-29 Thread george brida
Dear friends,
I have a csv data entitled GFS in the following path:
c:\TEG
This data is attached with this mail.
When I wrote the following lines:

y=read.csv(c:\\TEG\\GFS.csv, header=FALSE, sep=;)
  purtest(y, pmax = 4, exo = intercept, test = hadri)

I obtained the following message:

Error in Math.factor(x) : cumsum not meaningful for factors
In addition: There were 50 or more warnings (use warnings() to see the
first 50)

where's the problem? can you please help me
Thank you in advance
George
